Section 1 — The text of the Shulchan Aruch
The 6 seifim of Rav Yosef Karo
Siman רמ״ז of the Mechaber contains 6 seifim that lay out the conditions under which a Yisrael may entrust a letter or an object to a non-Jewish carrier before Shabbos. The hagahos of the Rema (Poland, 1572) are integrated into the standard text and are marked by הג״ה.
Seif Alef — The general rule
שולח אדם אגרת ביד עכו"ם ואפי' בע"ש עם חשיכה והוא שקוצץ לו דמים ובלבד שלא יאמר לו שילך בשבת ואם לא קצב אי לא קביע בי דואר (פי' איש ידוע שכל כתב אליו יובל והוא משלחם למי ששלוח אליו) במתא אסור לשלוח אפילו מיום ראשון ואי קביע בי דואר במתא משלחין אפי' בע"ש והוא שיהא שהות ביום כדי שיוכל להגיע לבית הסמוך לחומה: הגה ויש מתירין אפי' לא קצץ ואפילו לא קבוע בי דואר במתא אם משלחו ביום ה' או קודם לכן (טור) ויש לסמוך עלייהו אם צריכין לכך:
A man may send a letter with a non-Jew, even on erev Shabbos at nightfall — provided he settles a price with him (ketzitzah), and provided he does not tell him to travel on Shabbos. And if he did not fix a price: if no mail-collector (bei doar) [explanation: a known man to whom every letter is brought, and who forwards it to its addressee] is established in the town — it is forbidden to send even from Sunday; and if a bei doar is established in the town — one may send even on erev Shabbos, provided there is enough time in the day for him to reach the house adjoining the wall [of the destination town]. Hagahah of the Rema: And some permit even if he did not settle a price, and even if no bei doar is established in the town, if he sends it on Thursday or earlier (Tur); and one may rely on them in case of need.
The central idea of Seif Alef: sending a letter through a non-Jew is in principle permitted, and the Mechaber opens two tracks that do not stack. With a ketzitzah (a per-task price settled in advance) one sends even on erev Shabbos at nightfall, and no bei doar is required at all. Only in the absence of a ketzitzah — ואם לא קצב — does the question of the bei doar open: with no established bei doar in the town it is forbidden even from Sunday, and with an established bei doar one sends even on erev Shabbos, provided enough of the day remains. The Rema, for his part, dispenses with both — neither ketzitzah nor bei doar — through Thursday inclusive.
What this seif says:
- A letter may be entrusted to a non-Jew, even at nightfall — שולח אדם אגרת ביד עכו״ם ואפי׳ בע״ש עם חשיכה.
- On two conditions — והוא שקוצץ לו דמים ובלבד שלא יאמר לו שילך בשבת.
- And an established post changes everything — ואי קביע בי דואר במתא משלחין אפי׳ בע״ש.
- Rama: and a broader view, to be relied on at need — ויש לסמוך עלייהו אם צריכין לכך.
Seifim Beis through Vav — refinements and exceptions
| Seif | Topic | Position |
|---|---|---|
| ב׳ (2) | When one promises vaguely (without specifying the price) | If one said "I'll pay you" without a precise sum → treated as ketzitzah; but if nothing was said at all → forbidden |
| ג׳ (3) | When the non-Jew is a day-laborer (sachir yamim) | On erev Shabbos: forbidden (it looks as if the Yisrael asked him for Shabbos) |
| ד׳ (4) | When the non-Jew transports for free | The Mechaber is mattir (equivalent to ketzitzah) — the Rema brings a view that forbids |
| ה׳ (5) | When the non-Jew is going there on his own | Permitted in all cases — he is traveling for his own purposes |
| ו׳ (6) | Yearly employee as a general worker | Forbidden to send him with a letter on erev Shabbos (the Rema brings a lenient view) |
The whole siman revolves around a single structural question: when the non-Jew carries the letter on Shabbos, is he doing it as the agent of the Yisrael (שלוחו של ישראל) or for his own interest (אדעתא דנפשיה)? The 6 seifim apply this test to 6 borderline cases.
Section 2 — General context
Why this siman, what is the question?
What is this siman about?
Our siman addresses a very concrete situation: a Yisrael wants to send a letter, a package, or a piece of merchandise through a non-Jew (typically a carrier, a postal worker, a delivery man). The handover happens before Shabbos, but the transport will cross Shabbos — possibly even arriving on Shabbos itself.
The fundamental question: may this be permitted, or does it violate the issur of אמירה לעכו״ם (asking a non-Jew to perform melacha for a Yisrael on Shabbos)?
Link with the previous siman (רמ״ו)
Siman רמ״ו dealt with the lending and renting of objects to a non-Jew over Shabbos. There we were dealing with shvisas kelim (the rest of objects) and schar Shabbos (profit of Shabbos).
Our siman רמ״ז tackles a different angle: no longer the renting of an object to be used, but the sending of an object to be transported. The question is no longer "the non-Jew makes my kli work on Shabbos" but "the non-Jew himself performs a melacha on Shabbos with my object on his back".
Both simanim touch the same nerve: when does the non-Jew act as the agent of the Yisrael (= problem of amirah l'akum)? Siman רמ״ו solved it through havla'ah (inclusion in a multi-day package). Our siman רמ״ז solves it through ketzitzah (a per-task fixed price).
The underlying question
The issur of אמירה לעכו״ם is rabbinic (d'rabbanan). The Rishonim give three reasons:
| Source | Reason for the issur |
|---|---|
| Mechilta (on Yisro) | The passuk לא תעשה כל מלאכה (Shemos 20:10) — including by means of an agent |
| The shelichus approach | The non-Jew would be the Yisrael's agent — שלוחו של אדם כמותו, "a man's agent is like himself" (משנה ברכות ה׳:ה׳) |
| Rambam (Hilchos Shabbos 6:1) | So that Shabbos should not become light in their eyes — כדי שלא תהיה שבת קלה בעיניהן (רמב״ם הלכות שבת ו:א) |
The conceptual structure of the siman: as soon as the non-Jew is visibly acting for the Yisrael, we are within the issur of amirah. But if he is acting for his own interest (because he is paid per task, or because he was making the trip anyway), he steps out of the agency relationship and the sending becomes permitted.
Section 3 — First key concept
קציצה — ketzitzah, the fixed price
What is ketzitzah?
קציצה (ketzitzah) — from the root קצץ, "to cut, to fix" — is the act of settling a precise price with the non-Jew for the task to be performed, before he begins. Once this price is fixed, the non-Jew no longer acts in a logic of service to the Yisrael — he acts to collect his payment.
Why ketzitzah changes everything
With a firm ketzitzah:
- The non-Jew knows he will be paid a fixed amount, regardless of when he delivers
- He therefore has an interest in delivering quickly in order to move on to another client
- If he delivers on Shabbos, it is not because the Yisrael pushed him to — it is his own logistical choice
- So the outside observer does not see the Yisrael behind the melacha of Shabbos
Without ketzitzah:
- The non-Jew has no defined constraint
- If he hurries to deliver on Shabbos, it is to please the Yisrael
- He visibly becomes the agent of the Yisrael
- The issur of אמירה לעכו״ם applies
« בְּעִינַן דַּוְקָא שֶׁיִּקְצוֹב לוֹ דָּמִים בְּעַד מְלַאכְתּוֹ, דְּאָז אַדַּעְתֵּיהּ דְּנַפְשֵׁיהּ קָעָבִיד וְלֹא בִּשְׁבִיל יִשְׂרָאֵל » (מ״ב רמ״ז:א)
Mishnah Berurah (1): One must specifically settle a price for his work — for then he acts for his own interest and not for the Yisrael.
To verify whether the ketzitzah is valid:
- Is the price set in advance? ✓
- Is it independent of the delivery timing? ✓
- Is it certain (not a "we'll see")? ✓
Section 4 — Second key concept
אדעתא דנפשיה — adata d'nafshei, acting for oneself
What is adata d'nafshei?
אדעתא דנפשיה (adata d'nafshei) — literally "according to his own intention" — is the halachic test of perception. The question: when one observes the non-Jew performing his melacha on Shabbos, is he visibly serving a Yisrael, or is he visibly acting for his own interest?
The practical test
To apply the test, one asks:
| Criterion | If YES | If NO |
|---|---|---|
| Does the non-Jew have his own interest in performing the task? | adata d'nafshei — permitted | Service to the Yisrael — forbidden |
| Would he have made this trip anyway? | adata d'nafshei — permitted | Specific service — forbidden |
| Is he paid per task in advance? | adata d'nafshei — permitted | Without a fixed payment — suspect |
| Can an outside observer detect his own interest? | OK | nireh k'shlucho — forbidden |
« אַדַּעְתֵּיהּ דְּנַפְשֵׁיהּ קָעָבִיד בִּשְׁבִיל שְׂכִירוּתֵיהּ » (מ״ב רמ״ז:ג)
Mishnah Berurah (3): He acts for his own interest, on account of his wages.
Adata d'nafshei is the consequence of the ketzitzah. The ketzitzah is the objective mechanism (the priced contract); the adata d'nafshei is the visible effect (the non-Jew appears to act for himself). The two are linked: without ketzitzah, no adata; with a firm ketzitzah, the adata materializes.
Section 5 — Third key concept
קביעות בי דואר — kvi'us bei doar, a fixed mail station
What is kvi'us bei doar?
בי דואר (bei doar) — literally "the house of the post" — is a professional mail-collector in the destination city, who receives all letters and redistributes them.
קביעות (kvi'us) = that he be fixed and stationed permanently at that place.
קביעות (kvi'us) = that he be fixed and stationed permanently at that place.
Why this condition? The Mechaber is concerned that if the addressee cannot be found on arrival, the non-Jew would be forced to run after him on Shabbos — and there, the extra work is clearly caused by the Yisrael's mission.
Note — this condition is not a general one. It opens only where there has been no ketzitzah: the seif prefaces it with ואם לא קצב. Where a price has been settled, the Mechaber permits the sending even on erev Shabbos at nightfall without raising the question of the bei doar at all. See the structure of the seif.
Modern application
The modern equivalent of the בי דואר:
Conversely: if the non-Jew has to deliver "by hand" to a mobile person (uncertain residence), it is less mattir.
Position of the Rema
The Rema brings a more lenient view, and its term is Thursday inclusive: one is mattir to send even without a ketzitzah and even if the bei doar is not established, provided the sending goes out on the fifth day or earlier.
« ויש מתירין אפי׳ לא קצץ ואפילו לא קבוע בי דואר במתא אם משלחו ביום ה׳ או קודם לכן » (רמ״א אורח חיים רמ״ז:א)
The logic is the Mishnah Berurah's: once one is somewhat removed from Shabbos, the sending no longer looks like the Yisrael's errand.
« אבל מופלג מן השבת קצת לא מחזי כאומר לו עשה מלאכה בשבת ולפיכך אין לאסור כ״א ביום ע״ש » (מ״ב רמ״ז:י)
Practically:
- 📅 Sunday through Thursday inclusive → according to the Rema one may send even without a ketzitzah and even without kvi'us, and he himself adds the reservation: if one needs to
- 📅 Friday → the Rema's heter no longer applies. One then needs either a firm ketzitzah — and that suffices — or, failing that, an established bei doar and enough of the day for the delivery to reach the destination city before Shabbos
Section 6 — Seif א
The general framework: ketzitzah, or bei doar in its absence
שׁוֹלֵחַ אָדָם אִגֶּרֶת בְּיַד עַכּוּ״ם, וַאֲפִלּוּ בְּעֶרֶב שַׁבָּת עִם חֲשֵׁיכָה, וְהוּא שֶׁקּוֹצֵץ לוֹ דָּמִים, וּבִלְבַד שֶׁלֹּא יֹאמַר לוֹ שֶׁיֵּלֵךְ בְּשַׁבָּת. וְאִם לֹא קָצַב: אִי לֹא קְבִיעַ בֵּי דוֹאַר [פֵּירוּשׁ: אִישׁ יָדוּעַ שֶׁכָּל כְּתָב אֵלָיו יוּבַל, וְהוּא מְשַׁלְּחָם לְמִי שֶׁשָּׁלוּחַ אֵלָיו] בְּמָתָא — אָסוּר לִשְׁלוֹחַ אֲפִלּוּ מִיּוֹם רִאשׁוֹן; וְאִי קְבִיעַ בֵּי דוֹאַר בְּמָתָא — מְשַׁלְּחִין אֲפִלּוּ בְּעֶרֶב שַׁבָּת, וְהוּא שֶׁיְּהֵא שָׁהוּת בַּיּוֹם כְּדֵי שֶׁיּוּכַל לְהַגִּיעַ לַבַּיִת הַסָּמוּךְ לַחוֹמָה.
הגה: וְיֵשׁ מַתִּירִין אֲפִלּוּ לֹא קָצַץ, וַאֲפִלּוּ לֹא קָבוּעַ בֵּי דוֹאַר בְּמָתָא, אִם מְשַׁלְּחוֹ בְּיוֹם ה' אוֹ קוֹדֶם לָכֵן (טור), וְיֵשׁ לִסְמוֹךְ עֲלַיְיהוּ אִם צְרִיכִין לְכָךְ.
הגה: וְיֵשׁ מַתִּירִין אֲפִלּוּ לֹא קָצַץ, וַאֲפִלּוּ לֹא קָבוּעַ בֵּי דוֹאַר בְּמָתָא, אִם מְשַׁלְּחוֹ בְּיוֹם ה' אוֹ קוֹדֶם לָכֵן (טור), וְיֵשׁ לִסְמוֹךְ עֲלַיְיהוּ אִם צְרִיכִין לְכָךְ.
A man may send a letter with a non-Jew, even on erev Shabbos at nightfall — provided he settles a price with him (ketzitzah), and provided he does not tell him to travel on Shabbos. And if he did not fix a price: if no mail-collector (bei doar) [explanation: a known man to whom every letter is brought, and who forwards it to its addressee] is established in the town — it is forbidden to send even from Sunday; and if a bei doar is established in the town — one may send even on erev Shabbos, provided there is enough time in the day for him to reach the house adjoining the wall [of the destination town]. Hagahah of the Rema: And some permit even if he did not settle a price, and even if no bei doar is established in the town, if he sends it on Thursday or earlier (Tur); and one may rely on them in case of need.
What is this seif about?
Seif Alef sets out the governing rule of the whole siman. The Mechaber permits sending a letter (or, by extension, an object) through a non-Jew even on erev Shabbos at nightfall — in other words, even at a seemingly dangerous moment when the risk that the delivery will spill over into Shabbos is very real. This heter rests on the ketzitzah; and the seif goes on to govern, in the absence of a ketzitzah, a second track — that of the bei doar.
The halachic question
Sending a letter through a non-Jew triggers the issur of אמירה לעכו״ם (asking a non-Jew for a melacha of Shabbos). How can the Mechaber be mattir this sending even though the transport will cross Shabbos? The answer lies in the change of status of the non-Jew: under certain conditions, he ceases to act as the agent of the Yisrael (shaliach) and acts for his own interest (adata d'nafshei).
The structure of the seif — ketzitzah, or bei doar in its absence
The seif does not set out a list of conditions to be stacked, but two regimes, and the words that divide them stand in the text: ואם לא קצב, "and if he did not fix a price".
First regime — there is a ketzitzah. The sending is then permitted even on erev Shabbos at nightfall, and no bei doar is required.
« שולח אדם אגרת ביד עכו״ם ואפי׳ בע״ש עם חשיכה והוא שקוצץ לו דמים » (שולחן ערוך אורח חיים רמ״ז:א)
Two reservations come with it. The first is in the seif itself: he must not tell him to travel on Shabbos.
« ובלבד שלא יאמר לו שילך בשבת » (שולחן ערוך אורח חיים רמ״ז:א)
The second comes from the Mishnah Berurah, which explains what im chasheicha means: the non-Jew must have left the Yisrael's house before Shabbos comes in.
« היינו בעוד שהשמש זורח וגם צריך שיצא הא״י מפתח ביתו של ישראל קודם השבת » (מ״ב רמ״ז:ב)
Second regime — there is no ketzitzah. It is there alone that the bei doar enters, and it governs two opposite outcomes. With no established bei doar in the town, the issur is not confined to Friday: it runs from Sunday.
« ואם לא קצב אי לא קביע בי דואר… במתא אסור לשלוח אפילו מיום ראשון » (שולחן ערוך אורח חיים רמ״ז:א ; the ellipsis covers the word-gloss on בי דואר inserted here by the Shulchan Aruch — פי׳ איש ידוע שכל כתב אליו יובל והוא משלחם למי ששלוח אליו)
With an established bei doar, on the other hand, one sends even on erev Shabbos — on condition that enough of the day remains to reach the first house adjoining the wall of the destination city.
« ואי קביע בי דואר במתא משלחין אפי׳ בע״ש והוא שיהא שהות ביום כדי שיוכל להגיע לבית הסמוך לחומה » (שולחן ערוך אורח חיים רמ״ז:א)
Why such stringency when there is no bei doar? The Mishnah Berurah says it: we fear the non-Jew will not find the addressee and will have to chase after him on Shabbos.
« דשמא לא ימצאנו הא״י ויצטרך לילך אחריו בשבת » (מ״ב רמ״ז:ה)
The table of opinions
| Position | Rule | Logic |
|---|---|---|
| Mechaber (stam) | With ketzitzah: permitted even on erev Shabbos, with no bei doar required. Without ketzitzah: an established bei doar and enough of the day are needed, failing which it is forbidden from Sunday | Without ketzitzah and without bei doar, the non-Jew risks not finding the addressee and chasing after him on Shabbos |
| Rema (yesh mattirin) | Through Thursday inclusive: neither ketzitzah nor bei doar is required, with his own reservation — if one needs to | Sufficiently removed from Shabbos, the sending does not look like the Yisrael's errand |
| Mishnah Berurah | Follows the Mechaber as the rule; accepts the Rema as Ashkenazi practice | The test remains: nireh k'shlucho (appears as his agent) |
Practical pesak: on Friday, when the Rema's heter no longer applies, the sending comes back to one of the Mechaber's two tracks:
- Settle a price in advance (ketzitzah) with the carrier — this is the base track and it suffices; all that remains is not to ask him to travel on Shabbos, and that he leave the house before Shabbos comes in
- Failing a ketzitzah: hand it to an established collecting operator (post office, FedEx hub, etc.) and have enough of the day left to reach the destination city before Shabbos. With neither a settled price nor an established operator, the sending is forbidden — and forbidden from Sunday, not merely on Friday
Case A — Sending USPS Friday morning to a city across the country: the rate is settled in advance, so ketzitzah ✓ — and that suffices for the Mechaber's first track, with no need to ask about the bei doar. The letter leaves the house Friday morning (departure before Shabbos ✓), and nobody is asked to carry on Shabbos. → Permitted.
Case B — Letter handed to a non-Jewish neighbor who "will swing by the area" Friday evening: no price settled (ketzitzah ✗) — so we fall into the second regime. And there, no established collector at destination (bei doar ✗) → forbidden, and it would have been forbidden from Sunday. The Rema's heter, which would have covered the case through Thursday, no longer applies on a Friday evening.
To remember:
- Seif Alef is the matrix seif of the whole siman.
- Two regimes, not three cumulative conditions: with a ketzitzah, permitted even on erev Shabbos, with no bei doar; without a ketzitzah, an established bei doar and enough of the day are needed, failing which it is forbidden from Sunday.
- Two reservations attach to the ketzitzah: not to tell him to travel on Shabbos, and that he be out of the house before Shabbos comes in (מ״ב רמ״ז:ב).
- The Rema dispenses with both — ketzitzah and bei doar — through Thursday inclusive, and only if one needs to.
- The ultimate test: is the non-Jew visibly acting for himself or for the Yisrael?
Comprehension question: Why does the ketzitzah suffice, on its own, to permit the sending even on erev Shabbos at nightfall? And why does the question of the bei doar open only once no price has been settled?
Section 7 — Seif ב
The implicit ketzitzah: promising without specifying
ואם התנה עמו שיתן לו שכרו אף על פי שלא פירש כמה יתן לו דינו כקוצץ דסמכיה דעתיה דעכו"ם ובדידיה קא טרח אבל בסתם אע"פ שיש בדעתו שיתן לו שכר אסור דלא סמכיה דעתיה ובישראל קא טרח:
If one has stipulated with him that he will give him his wages, even without specifying how much — it is treated as a ketzitzah. For the non-Jew relies upon the payment (samcha da'atei) even without knowing the exact amount, and works for himself. But when nothing is stipulated, even if one has the intention to pay him, it is forbidden — for he does not rely on the payment and works for the Yisrael.
What is this seif about?
Having laid down the general rule (ketzitzah required), the Mechaber clarifies what counts as ketzitzah. The classic ketzitzah is a stated amount ("I'll give you $50"). But what happens if one simply says "I'll pay you" without naming a price? Or worse, if one says nothing at all, but intends to pay?
The halachic question
Is the ketzitzah an objective numeric contract (in which case a vague commitment does not count), or rather a state of mind in the non-Jew who knows he will be paid (in which case it is enough that he relies on the payment)?
The Mechaber's distinction
| Situation | Status | Reason |
|---|---|---|
| Explicit commitment, no figure ("I'll pay you") | = ketzitzah (permitted) | samcha da'atei — the non-Jew relies on the payment |
| No commitment but intent to pay | Forbidden | lo samcha da'atei — the non-Jew does not know he'll be paid, so he is working for the Yisrael |
| Firm numeric commitment | = ketzitzah (permitted) | Clearest case |
Practical pesak: what makes the ketzitzah halachically valid is not the numeric figure, but the existence of a commitment of payment communicated to the non-Jew. The decisive criterion is the non-Jew's state of mind: does he rely on the payment? If yes (even without knowing the amount), he is acting for himself → permitted. If no, he is acting for the Yisrael → forbidden.
Case A — "I'll pay you well" without specifying how much: said to the carrier, this is a valid ketzitzah. He knows he'll be paid and is relying on that.
Case B — A favor done by a neighbor without anything being said, while you intend to invite him to dinner in thanks: no ketzitzah. An unexpressed intention does not change the non-Jew's status — he believes he is acting for the Yisrael for free.
Case C — Standard market rate (e.g. "certified mail" at the post office, where everyone roughly knows the price): equivalent to an explicit ketzitzah, since the non-Jew knows what to expect.
To remember:
- Ketzitzah = a communicated commitment, not necessarily numeric.
- The decisive criterion: samcha da'atei (the non-Jew is relying on the payment).
- An unexpressed intention = no ketzitzah.
- A vague but real commitment ("I'll pay you") = sufficient ketzitzah.
Comprehension question: If ketzitzah is measured by the non-Jew's state of mind, what happens in the case where the non-Jew assumes he will be paid even without anyone saying anything (for example a professional courier)? How does one decide between these two cases?
Section 8 — Seif ג
What this seif says:
- Promising a wage without naming a sum counts as a fixed contract — ואם התנה עמו שיתן לו שכרו אף על פי שלא פירש כמה יתן לו דינו כקוצץ.
- And all turns on what the non-Jew is relying upon — דסמכיה דעתיה דעכו״ם ובדידיה קא טרח.
- Left unsaid, he labours for the Jew — אבל בסתם אע״פ שיש בדעתו שיתן לו שכר אסור דלא סמכיה דעתיה ובישראל קא טרח.
The day-laborer (sachir yamim)
אם שכרו לימים דבר קצוב בכל יום בהליכתו ובחזרתו אלא שאינו מקפיד עמו מתי ילך אם הוא בע"ש אסור דכשיוצא בשבת נראה כאלו התנה עמו כך:
If one hired him by the day, with a fixed wage for each day of round-trip travel, without minding the exact timing — on erev Shabbos it is forbidden, because when he goes out on Shabbos it looks as if one had agreed to that with him.
What is this seif about?
The Mechaber now refines the case of the carrier who is salaried by the day — not per task. Here, the non-Jew receives a fixed amount per day, but the Yisrael does not specify on which day he must leave. What happens if the non-Jew chooses to leave late on Friday, knowing that he will continue his journey into Shabbos?
The halachic question
Seif Alef dealt with the per-task carrier: his payment is independent of the day. But the sachir yamim is paid per day. This resembles a ketzitzah (fixed price), but the timing is flexible. The risk: if the Yisrael sends him on Friday leaving the timing free, the observer will conclude that the Yisrael specifically engaged him to leave on Shabbos.
The Mechaber's test
Practical pesak: even with a daily payment that is perfectly fixed:
- Sending him on a Friday with an uncertain margin → forbidden, because the Shabbos departure looks arranged
- Sending him earlier in the week → permitted (the link with Shabbos is broken)
Case A — Independent courier paid per run whom I approach on Friday at 3pm to deliver "whenever he can": forbidden according to this seif, since he might leave on Shabbos with no timing constraint.
Case B — Same courier engaged on Thursday for delivery "in the coming days": permitted — the Mishnah Berurah writes this expressly of the sachir yamim at ס״ק י״ד. The proximity with Shabbos is broken, the link of appearance is severed.
To remember:
- The sachir yamim is paid by the day, not per task.
- His payment is fixed, but the timing is left open.
- Friday = forbidden (appearance of a specific sending for Shabbos).
- Thursday and earlier = permitted (מ״ב רמ״ז:י״ד).
Comprehension question: Why is the sachir yamim more problematic than the simple per-task worker, given that he also has fixed payment? What nuance tips the seif into the issur?
Section 9 — Seif ד
What this seif says:
- The day-labourer: not caring when he sets out is what undoes it — אם שכרו לימים דבר קצוב בכל יום בהליכתו ובחזרתו אלא שאינו מקפיד עמו מתי ילך אם הוא בע״ש אסור.
- And the reason is appearance — דכשיוצא בשבת נראה כאלו התנה עמו כך.
Free transport: the non-Jew who acts out of gratitude
(אם) העכו"ם מוליך הכתב בחנם אפילו נתנה לו בערב שבת מותר שהרי העכו"ם מאליו הוא עוש' זה ואינו אלא להחזיק טובה לישראל מפני מה שקיבל ממנו והו"ל כאלו קצץ: הגה ויש חולקים וסבירא להו דכל שעושה בחנם אסור וטוב להחמיר אבל במקום שהעכו"ם מתחיל עם הישראל לומר שילך לו בחנם ודאי דעתו על הטובה שקיבל ממנו ושרי (ב"י):
(If) the non-Jew carries the letter for free — even if one gave it to him on erev Shabbos, it is permitted: for the non-Jew does this on his own, and only to show gratitude to the Jew for what he received from him — so it is as if he had settled a price. Hagahah of the Rema: Some disagree and hold that whatever he does for free is forbidden — and it is good to be stringent. But where the non-Jew takes the initiative to tell the Jew that he will go for him for free, his intention is certainly on the favor he received from him — and it is permitted (ב״י).
What is this seif about?
Seif Daled presents a paradoxical case: free transport. At first glance, without payment the non-Jew has no material interest — and he should therefore be considered an agent of the Yisrael. But the Mechaber turns the perspective around: if the non-Jew acts out of gratitude for a favor the Yisrael previously did him, he is in fact acting for himself (to discharge his moral debt).
The halachic question
How can the free case be mattir? The Mechaber's logic is subtle: gratitude (hachzakas tovah) is an internal motivation belonging to the non-Jew himself. He is not doing the letter for the Yisrael but to discharge a debt of gratitude. It is a non-monetary form of adata d'nafshei.
The Mechaber / Rema dispute
| Position | Status of free transport | Logic |
|---|---|---|
| Mechaber | Permitted (even on erev Shabbos) | The non-Jew acts out of gratitude → non-monetary adata d'nafshei |
| Rema (yesh cholkin) | Forbidden; it is good to be machmir (v'tov l'hachmir) | Without payment, the observer does not perceive the personal interest — he thinks the non-Jew is serving the Yisrael |
| Mishnah Berurah | Follows the Rema: better to make a small symbolic ketzitzah | Practical solution: convert the situation into a minimal ketzitzah |
Practical pesak: according to the Rema (followed by Ashkenazi practice and most poskim):
- When a non-Jew offers to transport for free, it is better to offer him a symbolic payment (a bottle of water, a tip, a small gift)
- This turns the situation into a minimal ketzitzah
- The outside observer then clearly perceives the non-Jew's own interest
Case A — A non-Jewish neighbor offers to mail my letter "since he's going there anyway": according to the Mechaber, permitted. According to the Rema, better to give him something small in thanks (a stamp, coffee, etc.).
Case B — A friendly delivery man offers a "free service" for Shabbos without any payment in return: according to the Rema, forbidden until a symbolic ketzitzah is formalized. Offering him $5 or some product resolves the difficulty.
To remember:
- The Mechaber permits free transport motivated by gratitude.
- The Rema recommends a minimal ketzitzah in every case.
- The universal solution: always give something to the carrier, even symbolic.
- The underlying principle: make the non-Jew's own interest visible.
Comprehension question: Why does the Rema prefer to be machmir in this particular case, when the Mechaber's logic seems solid (gratitude as a self-motivated drive)? What general halachic principle seems to guide the Rema's position?
Section 10 — Seif ה
What this seif says:
- Carrying it for free counts as a fixed contract — it repays a kindness — ואינו אלא להחזיק טובה לישראל מפני מה שקיבל ממנו והו״ל כאלו קצץ.
- Rama: others forbid it, and it is good to be stringent — ויש חולקים וסבירא להו דכל שעושה בחנם אסור וטוב להחמיר.
- Except where the non-Jew himself offers — אבל במקום שהעכו״ם מתחיל עם הישראל לומר שילך לו בחנם ודאי דעתו על הטובה שקיבל ממנו ושרי.
The non-Jew goes on his own: the most lenient case
אם העכו"ם הולך מעצמו למקום אחר וישראל נותן לו אגרת מותר בכל גוונא:
If the non-Jew is going on his own to another place, and the Yisrael gives him a letter to carry along the way — permitted in every case.
What is this seif about?
Seif Hei presents the most lenient case of the whole siman. The non-Jew has not been sent by the Yisrael: he is going on his own (me'atzmo) to another destination. Seeing that he is heading there, the Yisrael hands him a letter along the way. The seif itself requires neither ketzitzah, nor an established bei doar, nor a time-margin. The Mishnah Berurah, however, does keep the margin: « ודוקא אם יש שהות להגיע שם מבעוד יום אבל אם אין שהות להגיע שם מבעוד יום אסור אף בזה » (מ״ב רמ״ז:י״ח).
The halachic question
Why is this case so clearly mattir? Because all the structural elements of the issur disappear:
- The Shabbos journey is not generated by the Yisrael's request — it would have taken place anyway
- The non-Jew is not acting as the Yisrael's agent — he is making his own trip
- The outside observer sees a traveler who is carrying a letter along the way, not a messenger traveling for the Yisrael
The essential test: the detour
Practical pesak: permitted in every case (b'chol gavna) — subject to a proviso the Mishnah Berurah states expressly: the non-Jew must not make a detour for the Yisrael's letter. If the non-Jew was going to Chicago anyway and I hand him a letter for Chicago = permitted. If he was supposed to swing through Chicago specifically for my letter = this is no longer the case of Seif Hei; the detour reinstates the service-to-the-Yisrael.
The Mishnah Berurah states this proviso in the name of the Beis Yosef, and states it as a prohibition: « ואם יודע שמרבה הדרך בשבילו אסור » (מ״ב רמ״ז:י״ז) — if one knows that the non-Jew is lengthening his route for the Yisrael, it is forbidden.
Case A — A non-Jewish neighbor drives to Boston on Tuesday; I ask him to drop off an envelope to an addressee in Boston: permitted with no further conditions.
Case B — The same neighbor drives to New York, but I ask him to make a 20-mile detour through Hartford for my letter: this is no longer Seif Hei. The detour transforms the sending into a specific service → the general rule then applies (ketzitzah, departure before Shabbos, etc.).
Case C — A non-Jewish guest staying at my home who is returning to his country: I entrust him with mail for a family there. Permitted in every case — he would have made the trip anyway.
To remember:
- Most lenient case of the siman: permitted b'chol gavna.
- The seif requires neither ketzitzah nor an established bei doar; the Mishnah Berurah nevertheless keeps the daytime margin (מ״ב רמ״ז:י״ח).
- The non-Jew is making his own trip — he carries the letter along the way.
- Essential limit: no specific detour for the Yisrael (otherwise Seif Hei no longer applies).
Comprehension question: If the non-Jew is going on his own, why is it still required that the Yisrael give him the letter before Shabbos? Why does this seif not also waive the "departure before Shabbos" condition?
Section 11 — Seif ו
What this seif says:
- If he is going of his own accord, all is permitted — אם העכו״ם הולך מעצמו למקום אחר וישראל נותן לו אגרת מותר בכל גוונא.
The yearly employee (sachir shanah): the permanent worker
מי שיש לו שכיר עכו"ם לשנה או יותר אסור לשלחו ערב שבת באגרת: הגה ומיהו אם לא שכרו רק בשליחות אגרת יש מתירין כמו שנתבאר לעיל סי' רמ"ד ס"ה:
One who has a non-Jewish employee hired for a year (or more) — it is forbidden to send him on erev Shabbos with a letter. Hagahah of the Rema: But if he was hired only for the letter-carrying service, some are mattir (cf. siman 244 seif 5).
What is this seif about?
Seif Vav examines a final borderline case: the permanent yearly employee (sachir shanah). The Yisrael has a fixed non-Jewish employee — a servant, a coachman, an all-purpose worker — paid annually for a range of services. May he be sent on Friday with a letter whose delivery will spill over into Shabbos?
The halachic question
At first glance, the sachir shanah also has a ketzitzah — his salary is fixed in advance. But here is the subtlety: his salary is global, not attached to this particular task. When he delivers the letter on Shabbos, he is not doing it for a specific amount tied to the transport — he is doing it because he is the Yisrael's employee. He is therefore acting as the Yisrael's agent, and not for his own interest in this task.
The table of opinions
| Position | Rule | Reasoning |
|---|---|---|
| Mechaber (stam) | Forbidden to send him on erev Shabbos with a letter | The global salary does not constitute a ketzitzah on this task — the employee appears as the Yisrael's agent |
| Rema (yesh mattirin) | Permitted if the employee was hired specifically for the letter-carrying service | Reference to siman 244 seif 5 — when the task defines the contract, the ketzitzah is attached to that task |
| Mishnah Berurah | Follows the Mechaber as the general rule; acknowledges the Rema's exception for professional couriers | Maintains the test of nireh k'shlucho |
Practical pesak:
- General employee (cleaning lady, chauffeur, multi-purpose servant) → do not send him on erev Shabbos with a letter whose delivery spills into Shabbos
- Dedicated courier (hired specifically for mail) → permitted according to the Rema
- The key distinction: is the task the object of the contract, or a service among others?
Case A — Permanent non-Jewish cleaning lady whom I ask "on the side" to mail a letter on Friday: forbidden according to the Mechaber, because she acts as the Yisrael's general employee.
Case B — A private courier of a messenger company whom my business pays annually specifically to deliver mail: permitted according to the Rema (the contract is dedicated to that task).
Case C — Seasonal non-Jewish worker hired for a particular mission (harvest, etc.) whom I ask on the side to deliver a letter on Friday: belongs to the same logic as the sachir yamim — forbidden on erev Shabbos.
To remember:
- Sachir shanah = global employee, paid for a range of services.
- His salary is not attached to the specific transport task.
- Mechaber: forbidden on erev Shabbos.
- Rema: permitted if hired specifically for the mail (referring to siman 244:5).
- Practically: use an outside service (post office, dedicated courier) rather than one's general employee.
Comprehension question: What is the conceptual difference between the sachir yamim of Seif Gimel and the sachir shanah of Seif Vav? Why do the two lead to the same verdict (forbidden on erev Shabbos) despite their contractual differences?
Section 12
The position of the Rema — what changes for an Ashkenazi
The Rema (Rav Moshe Isserles) adds three important leniencies for Ashkenazi practice:
Leniency 1 — Through Thursday inclusive, without ketzitzah or kvi'us
The Rema writes: ויש מתירין אפי׳ לא קצץ ואפילו לא קבוע בי דואר במתא אם משלחו ביום ה׳ או קודם לכן (רמ״א אורח חיים רמ״ז:א).
Through Thursday inclusive — yom hei is the fifth day of the week, that is, Thursday —, one is mattir to send a letter through a non-Jew even without a ketzitzah and even without an established bei doar. The Mishnah Berurah says it in so many words: ולדעת הרמ״א לעיל בהג״ה אפילו לא קצץ כלל מותר ביום ה׳ (מ״ב רמ״ז:י״ד).
And the Rema does not put this heter forward as his first-choice position: he attaches a reservation to it, ויש לסמוך עלייהו אם צריכין לכך (רמ״א אורח חיים רמ״ז:א).
Through Thursday inclusive — yom hei is the fifth day of the week, that is, Thursday —, one is mattir to send a letter through a non-Jew even without a ketzitzah and even without an established bei doar. The Mishnah Berurah says it in so many words: ולדעת הרמ״א לעיל בהג״ה אפילו לא קצץ כלל מותר ביום ה׳ (מ״ב רמ״ז:י״ד).
And the Rema does not put this heter forward as his first-choice position: he attaches a reservation to it, ויש לסמוך עלייהו אם צריכין לכך (רמ״א אורח חיים רמ״ז:א).
The logic: we are sufficiently far from Shabbos that no one will link the sending to melacha on Shabbos. The risk of nireh k'shlucho (appearance of agency) falls away.
Leniency 2 — Recommendation of ketzitzah even for free transport
As we saw in Seif Daled, the Rema says "v'tov l'hachmir" — it is good to be machmir and to always settle on a small payment, even if the non-Jew offers to transport for free.
Leniency 3 — Employee hired specifically for the mail
As we saw in Seif Vav, if one engaged the non-Jew specifically for the letter-carrying service (and not as a general employee), the Rema brings a lenient view referring to siman 244.
Mechaber vs Rema table:
| Case | Mechaber (Sefardi) | Rema (Ashkenazi) |
|---|---|---|
| Sending through Thursday inclusive, without ketzitzah and without an established bei doar | Forbidden from Sunday | Permitted at need (yesh mattirin) |
| Free transport on erev Shabbos | Permitted | Better to give a payment |
| Employee hired specifically for mail | Doubtful | Permitted (cf. 244:5) |
Section 13
Modern practical cases
Case 1 — USPS / standard mail
Case: I send a regular letter to an addressee in another state on Friday morning.
Analysis:
Analysis:
- Ketzitzah ✓ (the rate is fixed in advance by USPS)
- Kvi'us ✓ (central post offices are fixed bei doar)
- Departure before Shabbos ✓ (the letter leaves my house Friday morning)
Case 2 — Amazon Prime delivery Friday for Saturday
Case: I order a product Thursday with Prime delivery "Saturday before noon".
Analysis:
Analysis:
- Ketzitzah ✓ (delivery fees fixed at time of order)
- But! The delivery arrives on Shabbos itself
- And it is a physical package, not a simple letter — the receiving itself can pose a problem
- The order on Thursday is technically permitted (ketzitzah + enough margin for Friday delivery)
- But receiving a package on Shabbos is a separate question (siman 252 — not our subject here)
- Better to schedule the delivery outside Shabbos to avoid the cascade problem
Case 3 — FedEx express delivery Friday for Friday evening
Case: I send a package Friday morning with FedEx "delivery Friday before 6pm".
Analysis:
Analysis:
- Ketzitzah ✓ (fixed FedEx rate)
- Kvi'us ✓ (FedEx has permanent sorting centers)
- Time-margin: conceptually possible for it to arrive before Shabbos
Case 4 — Independent delivery man who offers his services for free
Case: a non-Jewish neighbor tells me "I'm passing through Boston tomorrow, I can carry your package for free".
Analysis:
Analysis:
- Mechaber: permitted (adata d'nafshei — he is making his own trip)
- Rema: it is good to offer a small symbolic payment
Case 5 — Email scheduled for Shabbos
Case: I write an email Friday morning and schedule it to be sent at 2pm on Shabbos.
Analysis:
Analysis:
- The sending is automatic (a machine, not a human non-Jew)
- No direct amirah l'akum
- But the addressee will see it on Shabbos, and some poskim are concerned about nireh b'Shabbos
Section 14
Practical synthesis of the siman
The two tracks for sending via a non-Jew:
- The ketzitzah track — a price settled in advance (a FedEx rate, an explicit promise, etc.). It permits the sending right up to erev Shabbos at nightfall, with no bei doar required. Two reservations: not to ask the non-Jew to travel on Shabbos, and that he be out of the house before Shabbos comes in.
- The bei doar track, failing a ketzitzah — an established mail-collector at destination, and enough of the day for the sending to reach the destination city before Shabbos. With neither one nor the other, it is forbidden from Sunday.
Practical decision table
| Situation | Conduct |
|---|---|
| I send a letter Sunday through Thursday | With a ketzitzah: permitted. Without one: the Mechaber requires an established bei doar, and the Rema dispenses even with that through Thursday inclusive, at need |
| I send a letter with no price settled at all and no established postal service | Forbidden according to the Mechaber from Sunday; the Rema permits it at need through Thursday inclusive, and no longer on Friday |
| I send a letter Friday before Shabbos | The Rema's heter no longer applies. With a firm ketzitzah: permitted, provided the non-Jew leaves before Shabbos comes in. Without one: an established bei doar and enough of the day to reach the destination city |
| I use USPS / FedEx / UPS | Permitted — the rate is fixed, the hubs are fixed, it's a professional service |
| A non-Jewish neighbor offers to carry for free | Permitted according to the Mechaber; according to the Rema, give a symbolic payment |
| My non-Jewish employee (yearly) — sending him on erev Shabbos | Forbidden, unless hired specifically for mail |
| The non-Jew is going there on his own | Permitted in every case (except a detour for the Yisrael) |
The 5 practical pillars of Siman רמ״ז
- Always settle a price in advance with the non-Jewish carrier (ketzitzah)
- Make sure the non-Jew leaves your house before Shabbos (kenisas haShabbos)
- Prefer professional services (post office, FedEx) over informal arrangements
- Do not send a permanent employee on erev Shabbos — use an outside service
- Do not explicitly ask the non-Jew to deliver on Shabbos (direct amirah = absolute issur)
Section 15
