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

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.
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, but under three cumulative conditionsketzitzah (fixed price), kvi'us (fixed addressee), and a time-margin (the delivery must be finishable before Shabbos). The Rema relaxes the condition of kvi'us from Sunday through Wednesday.

Seifim Beis through Vav — refinements and exceptions

SeifTopicPosition
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 freeThe Mechaber is mattir (equivalent to ketzitzah) — the Rema brings a view that forbids
ה׳ (5)When the non-Jew is going there on his ownPermitted in all cases — he is traveling for his own purposes
ו׳ (6)Yearly employee as a general workerForbidden 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.
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)?

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:

SourceReason for the issur
Mechilta (on Yisro)The passuk "כל מלאכה לא תעשה" (Shemos 20:10) — including by means of an agent
Rashi (Avodah Zarah 15a)The principle of שלוחו של אדם כמותו (a man's agent is like himself), applied to the non-Jew
Rambam (Hilchos Shabbos 6:1)So that Shabbos should not become "light" in the eyes of the Yisrael (קלות שבת בעיניו)
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.
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:

Without ketzitzah:

"בְּעִינַן דַּוְקָא שֶׁיִּקְצוֹב לוֹ דָּמִים בְּעַד מְלַאכְתּוֹ, דְּאָז אַדַּעְתֵּיהּ דְּנַפְשֵׁיהּ קָעָבִיד וְלֹא בִּשְׁבִיל יִשְׂרָאֵל" (משנה ברורה רמ״ז ס״ק 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:
  1. Is the price set in advance? ✓
  2. Is it independent of the delivery timing? ✓
  3. Is it certain (not a "we'll see")? ✓
If yes to all three → valid ketzitzah → the sending falls into the mattir case.
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:

CriterionIf YESIf NO
Does the non-Jew have his own interest in performing the task?adata d'nafshei — permittedService to the Yisrael — forbidden
Would he have made this trip anyway?adata d'nafshei — permittedSpecific service — forbidden
Is he paid per task in advance?adata d'nafshei — permittedWithout a fixed payment — suspect
Can an outside observer detect his own interest?OKnireh k'shlucho — forbidden
"אַדַּעְתֵּיהּ דְּנַפְשֵׁיהּ קָעָבִיד בִּשְׁבִיל שְׂכִירוּתֵיהּ" (משנה ברורה רמ״ז ס״ק 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.
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.

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.

Modern application

The modern equivalent of the בי דואר:
  • 🏢 The central post office of a city (always open during standard hours)
  • 🏬 An Amazon hub or FedEx depot (structural relay point)
  • 🏠 An addressee who does not move — a stable residential address
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: from Sunday through Wednesday (יום ראשון עד יום רביעי), one is mattir to send even if the bei doar is not fixed. The logic: we are far from Shabbos, so the observer does not link the sending with melacha on Shabbos.

Practically:
  • 📅 Sunday, Monday, Tuesday, Wednesday → one may send even without kvi'us (according to the Rema)
  • 📅 Thursday, Friday → one needs ketzitzah and kvi'us, or else a sufficient time-margin so that the delivery can be completed before Shabbos

The general framework: the 3 conditions of sending

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.
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. But this heter is conditioned on three cumulative requirements.

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 3 cumulative conditions

  1. Ketzitzah — a price settled in advance, fixed and certain
  2. Departure before Shabbos — the non-Jew leaves the Yisrael's house before Shabbos comes in (kenisas haShabbos)
  3. Either kvi'us bei doar, or a time-margin — either the addressee is a fixed mail-collector stationed in the target city, or the non-Jew has enough time to reach, before Shabbos, the "first house adjoining the wall" (= the entrance of the destination city)

The table of opinions

PositionRuleLogic
Mechaber (stam)3 cumulative conditions (ketzitzah + departure + kvi'us/margin)Without kvi'us or margin, the non-Jew risks running after the addressee on Shabbos → visible service to the Yisrael
Rema (yesh mattirin)From Sunday through Wednesday: no need for kvi'usFar from Shabbos, the observer does not connect with melacha of Shabbos
Mishnah BerurahFollows the Mechaber as the rule; accepts the Rema as Ashkenazi practiceThe test remains: nireh k'shlucho (appears as his agent)
Practical pesak: from Wednesday evening on, and especially Thursday-Friday, one needs cumulatively:
  1. Settle a price in advance (ketzitzah) with the carrier
  2. Make sure he leaves the house before Shabbos
  3. Either deliver to a fixed professional operator (post office, FedEx hub, etc.), or allow enough time to reach the destination city before Shabbos comes in
The key phrase of the Mechaber: "וַאֲפִלּוּ קָצַץ, אִם לֹא קָבוּעַ בִּי דּוֹאַר בְּאוֹתָהּ הָעִיר אָסוּר"ketzitzah alone is therefore not enough if the delivery timing remains uncertain.
Case A — Sending USPS Friday morning to a city across the country: fixed rate (ketzitzah ✓), the central post office acts as a fixed bei doar (kvi'us ✓), letter dropped off Friday morning (departure before Shabbos ✓). → Permitted according to the Mechaber and the Rema.
Case B — Letter handed to a non-Jewish neighbor who "will swing by the area" Friday evening: no price settled (ketzitzah ✗), no clear or fixed destination (kvi'us ✗). → Forbidden, since the non-Jew will appear as the Yisrael's agent.
To remember:
  • Seif Alef is the matrix seif of the whole siman.
  • Three cumulative conditions: ketzitzah + departure before Shabbos + (kvi'us OR time-margin).
  • The Rema relaxes the 3rd condition from Sunday through Wednesday.
  • The ultimate test: is the non-Jew visibly acting for himself or for the Yisrael?
Comprehension question: Why does the ketzitzah alone not suffice according to the Mechaber, given that it already represents a major shift in the relationship between the Yisrael and the non-Jew? What concern does the condition of kvi'us come to address?

The implicit ketzitzah: promising without specifying

וְאִם הִתְנָה עִמּוֹ שֶׁיִּתֵּן לוֹ שְׂכָרוֹ אַף עַל פִּי שֶׁלֹּא פֵּרֵשׁ כַּמָּה יִתֵּן לוֹ דִּינוֹ כְּקוֹצֵץ, דְּסַמְכֵיהּ דַּעְתֵּיהּ דְּעַכּוּ״ם וּבְדִידֵיהּ קָא טָרַח. אֲבָל בִּסְתָם אַף עַל פִּי שֶׁיֵּשׁ בְּדַעְתּוֹ שֶׁיִּתֵּן לוֹ שָׂכָר אָסוּר דְּלֹא סַמְכֵיהּ דַּעְתֵּיהּ וּבְיִשְׂרָאֵל קָא טָרַח.
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

SituationStatusReason
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 payForbiddenlo 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?

The day-laborer (sachir yamim)

אִם שְׂכָרוֹ לְיָמִים דָּבָר קָצוּב בְּכָל יוֹם בַּהֲלִיכָתוֹ וּבַחֲזִירָתוֹ, אֶלָּא שֶׁאֵינוֹ מַקְפִּיד עִמּוֹ מָתַי יֵלֵךְ — אִם הוּא בְּעֶרֶב שַׁבָּת אָסוּר, דִּכְשֶׁיּוֹצֵא בְּשַׁבָּת נִרְאֶה כְּאִלּוּ הִתְנָה עִמּוֹ כָּךְ.
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)
The reason: the immediate proximity of Shabbos makes the observer draw the natural inference — "he hired him last night, he leaves today on Shabbos — he must have asked him for Shabbos". On Tuesday or Wednesday, that inference falls away.
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 Wednesday morning for delivery "in the coming days": permitted. 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.
  • Late Friday = forbidden (appearance of a specific sending for Shabbos).
  • Earlier in the week = permitted (the link with Shabbos is broken).
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?

Free transport: the non-Jew who acts out of gratitude

(אִם) הָעַכּוּ״ם מוֹלִיךְ הַכְּתָב בְּחִנָּם, אֲפִלּוּ נְתָנָהּ לוֹ בְּעֶרֶב שַׁבָּת מֻתָּר, שֶׁהֲרֵי הָעַכּוּ״ם מֵאֵלָיו הוּא עוֹשֶׂה זֶה וְאֵינוֹ אֶלָּא לְהַחֲזִיק טוֹבָה לְיִשְׂרָאֵל מִפְּנֵי מַה שֶׁקִּיבֵּל מִמֶּנּוּ, וְהָוֵי לֵיהּ כְּאִלּוּ קָצַץ. הגה: וְיֵשׁ חוֹלְקִים וּסְבִירָא לְהוּ דְּכָל שֶׁעוֹשֶׂה בְּחִנָּם אָסוּר, וְטוֹב לְהַחְמִיר. אֲבָל בְּמָקוֹם שֶׁהָעַכּוּ״ם מַתְחִיל עִם הַיִּשְׂרָאֵל לוֹמַר שֶׁיֵּלֵךְ לוֹ בְּחִנָּם, וַדַּאי דַּעְתּוֹ עַל הַטּוֹבָה שֶׁקִּיבֵּל מִמֶּנּוּ — וְשָׁרֵי (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

PositionStatus of free transportLogic
MechaberPermitted (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 BerurahFollows the Rema: better to make a small symbolic ketzitzahPractical 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?

The non-Jew goes on his own: the most lenient case

אִם הָעַכּוּ״ם הוֹלֵךְ מֵעַצְמוֹ לְמָקוֹם אַחֵר וְיִשְׂרָאֵל נוֹתֵן לוֹ אִגֶּרֶת — מֻתָּר בְּכָל גַּוְנָא.
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. No ketzitzah needed, no kvi'us, no particular time-margin.

The halachic question

Why is this case so clearly mattir? Because all the structural elements of the issur disappear:

The essential test: the detour

Practical pesak: permitted in every case (b'chol gavna) — on one essential condition: 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 Beis Yosef (cited by the Mishnah Berurah) makes this essential proviso explicit: "ובלבד שלא יעשה בשבילו" — provided that he does not do this specifically for the Yisrael.

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.
  • No ketzitzah needed, no kvi'us, no margin.
  • 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?

The yearly employee (sachir shanah): the permanent worker

מִי שֶׁיֵּשׁ לוֹ שָׂכִיר עַכּוּ״ם לְשָׁנָה אוֹ יוֹתֵר — אָסוּר לְשַׁלְּחוֹ עֶרֶב שַׁבָּת בְּאִגֶּרֶת. הגה: וּמִיהוּ אִם לֹא שְׂכָרוֹ רַק בִּשְׁלִיחוּת אִגֶּרֶת יֵשׁ מַתִּירִין, כְּמוֹ שֶׁנִּתְבָּאֵר לְעֵיל סִי' 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

PositionRuleReasoning
Mechaber (stam)Forbidden to send him on erev Shabbos with a letterThe 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 serviceReference to siman 244 seif 5 — when the task defines the contract, the ketzitzah is attached to that task
Mishnah BerurahFollows the Mechaber as the general rule; acknowledges the Rema's exception for professional couriersMaintains 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?
The position of the Rema — what changes for an Ashkenazi

The Rema (Rav Moshe Isserles) adds three important leniencies for Ashkenazi practice:

Leniency 1 — Sunday through Wednesday without kvi'us

The Rema writes explicitly: "וְיֵשׁ מַתִּירִין בְּכָל גַּוְנָא מִיּוֹם רִאשׁוֹן וְעַד יוֹם רְבִיעִי, וַאֲפִלּוּ לֹא קָבוּעַ בִּי דּוֹאַר". From Sunday through Wednesday, one is mattir to send a letter through a non-Jew even without kvi'us bei doar.

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:
CaseMechaber (Sefardi)Rema (Ashkenazi)
Sending from Sunday through Wednesday without kvi'usForbidden (unless time-margin)Permitted (yesh mattirin)
Free transport on erev ShabbosPermittedBetter to give a payment
Employee hired specifically for mailDoubtfulPermitted (cf. 244:5)
Modern practical cases

Case 1 — USPS / standard mail

Case: I send a regular letter to an addressee in another state on Friday morning.
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)
Conduct: permitted according to the Mechaber and the Rema.

Case 2 — Amazon Prime delivery Friday for Saturday

Case: I order a product Thursday with Prime delivery "Saturday before noon".
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
Conduct:
  • 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:
  • Ketzitzah ✓ (fixed FedEx rate)
  • Kvi'us ✓ (FedEx has permanent sorting centers)
  • Time-margin: conceptually possible for it to arrive before Shabbos
Conduct: permitted. Even if in practice the package were to spill over slightly, the test of "mibe'od yom" (enough time before Shabbos at the origin) is satisfied.

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:
  • Mechaber: permitted (adata d'nafshei — he is making his own trip)
  • Rema: it is good to offer a small symbolic payment
Conduct (Ashkenazi): give a bottle of water or a symbolic $5 to convert into a ketzitzah.

Case 5 — Email scheduled for Shabbos

Case: I write an email Friday morning and schedule it to be sent at 2pm on Shabbos.
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
Conduct: a broader subject than our siman (also touches on automatic melacha). In practice, most contemporary poskim permit a scheduled email as long as the content is not for Shabbos use.
Practical synthesis of the siman
The 3 cumulative conditions to send via a non-Jew:
  1. Ketzitzah — a price settled in advance (a FedEx rate, an explicit promise, etc.)
  2. Departure before Shabbos — the non-Jew leaves the Yisrael's house before Shabbos comes in
  3. Either kvi'us (a fixed mail-collector at destination) or a time-margin (enough time to deliver before Shabbos)

Practical decision table

SituationConduct
I send a letter Sunday-Tuesday Permitted without issue (ketzitzah + departure before Shabbos suffice; the Rema even dispenses with kvi'us)
I send a letter Wednesday-Thursday Permitted with ketzitzah + kvi'us, or a sufficient time-margin
I send a letter Friday before Shabbos Permitted only with the 3 strict conditions (firm ketzitzah + kvi'us + margin)
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

  1. Always settle a price in advance with the non-Jewish carrier (ketzitzah)
  2. Make sure the non-Jew leaves your house before Shabbos (kenisas haShabbos)
  3. Prefer professional services (post office, FedEx) over informal arrangements
  4. Do not send a permanent employee on erev Shabbos — use an outside service
  5. Do not explicitly ask the non-Jew to deliver on Shabbos (direct amirah = absolute issur)
