A first approach to Siman 120: the 16 seifim of the Mehaber and the glosses of the Rama, Hebrew text with a fluent English translation. A mealtime vessel bought from a non-Jew becomes usable only after immersion in a mikveh (טבילת כלים) — even brand new, even perfectly clean. What remains to be settled is which vessels, which materials, which blessing, and what difference the mode of acquisition makes: purchase, loan, rental, pledge, or an order placed with a craftsman.

1. The Mehaber’s text — the 16 seifim

Siman 120 deals with an act every Jewish home performs: immersing in a mikveh the tableware bought from a non-Jew. The Mehaber (Rabbi Yosef Karo) unfolds it across sixteen seifim, and four distinct questions quickly emerge: which vessels are concerned and in what water (seifim 1-3); which materials and assemblies trigger the obligation (seifim 4-7); by what mode of acquisition it arises — purchase, loan, pledge, commission (seifim 8-11); and how the immersion is carried out, with its remedies (seifim 12-16). The Rama (Rabbi Moshe Isserles) adds his glosses (הגה), almost always in the same direction: where there is doubt, immerse — but without a blessing.

Group A — The obligation, its manner and its blessing (seifim 1-3)

Seif 1 — Which vessels require immersion, and in what water

הַקּוֹנֶה מֵהָעוֹבֵד כּוֹכָבִים כְּלֵי סְעוּדָה שֶׁל מַתְּכוֹ׳ אוֹ שֶׁל זְכוּכִית אוֹ כֵּלִים הַמְצוּפִּים בַּאֲבָר מִבִּפְנִים אַף עַל פִּי שֶׁהֵם חֲדָשִׁים צָרִיךְ לְהַטְבִּילָם בְּמִקְוֶה אוֹ מַעְיָין שֶׁל אַרְבָּעִים סְאָה (טוּר בְּשֵׁם סה״מ ועב״י): הגה י״א דְּכֵלִים הַמְצוּפִּים בַּאֲבָר אֲפִילּוּ בִּפְנִים יִטְבּוֹל בְּלֹא בְּרָכָה (ב״י בְּשֵׁם סמ״ק וְאָרוֹךְ) וְכֵן נוֹהֲגִין:
One who buys from a non-Jew mealtime vessels (כלי סעודה) of metal or glass, or vessels lined with tin on the inside (מצופים באבר)even if they are brand new — must immerse them in a mikveh or a spring of forty se'ah. Rama's gloss: some say that tin-lined vessels, even lined within, are immersed without a blessing; and such is the custom.
The starting point: immersion is neither a cleaning nor a kashering. The vessel may be brand new and never used — it still requires immersion. What changes is its status: it leaves the non-Jew's domain and enters Israel's. Two limits appear at once: the type of vessel (mealtime vessels) and the material (metal, glass, tin lining).

Seif 2 — Holding the vessel loosely: the concern of חציצה

צָרִיךְ שֶׁיְּהֵא הַכְּלִי רָפוּי בְּיָדוֹ בִּשְׁעַת טְבִילָה שֶׁאִם מְהַדְּקוֹ בְּיָדוֹ הָוֵי חֲצִיצָה וְאִם לִחְלֵחַ יָדוֹ בְּמַיִם תְּחִילָּה אֵין לָחוּשׁ. (וְדַוְקָא שֶׁלִּחְלֵחַ יָדָיו בְּמֵי מִקְוֶה אֲבָל לֹא בְּמַיִם תְּלוּשִׁים) (מַשְׁמַע מִמָּרְדְּכַי פֶּרֶק הַשּׂוֹכֵר):
The vessel must be held loosely in the hand (רפוי בידו) during the immersion: if one grips it tightly, the hand becomes a חציצה (interposition). But if one first moistened one's hand with water, there is no concern. Rama's gloss: provided the hands were moistened with the mikveh's own water, and not with detached water (מים תלושים).
What this seif reveals: immersing vessels follows the ordinary rules of the mikveh — including חציצה. A hand clenched on the handle interposes exactly as dirt under a fingernail would. The remedy is elegant: a hand already wet with the mikveh's water no longer separates, since the water on the hand and the water of the pool are one water.

Seif 3 — The wording of the blessing: כלי or כלים

יְבָרֵךְ עַל טְבִילַת כְּלִי וְאִם הֵם שְׁנַיִם אוֹ יוֹתֵר מְבָרֵךְ עַל טְבִילַת כֵּלִים:
One recites עַל טְבִילַת כְּלִי (“on the immersion of a vessel”); and if there are two or more, one says עַל טְבִילַת כֵּלִים, in the plural.
A point of wording: the Shulchan Aruch fixes the formula in the singular or plural according to the number of vessels. This is the kind of detail that matters in practice: one does not recite a “generic” blessing but one that matches the act performed.

Group B — Which vessels are obligated and which are exempt (seifim 4-7)

Seif 4 — Trivets and griddles: what carries the pot, what carries the food

טריפיד״ש שֶׁשּׁוֹפְתִים עֲלֵיהֶם קְדֵירוֹת אֵינָם טְעוּנוֹת טְבִילָה אֲבָל פדיליא״ש טְעוּנוֹת טְבִילָה מִפְּנֵי שֶׁנּוֹתְנִים עֲלֵיהֶם הַמַּאֲכָל עַצְמוֹ:
Trivets (טריפיד״ש) upon which pots are set do not require immersion; but baking plates (פדיליא״ש) do require it, because the food itself is placed upon them.
The emerging criterion: what decides is not the metal but the use. A trivet never touches the food: it carries the pot. A baking plate receives the food itself. Hold on to this dividing line: does the vessel come into contact with the food?

Seif 5 — The sheḥita knife and vessels of an intermediate stage

סַכִּין שֶׁל שְׁחִיטָה (אוֹ סַכִּין שֶׁמַּפְשִׁיטִין בּוֹ) (אָרוֹךְ) יֵשׁ מִי שֶׁאוֹמֵר שֶׁאֵינוֹ צָרִיךְ טְבִילָה: הגה וְיֵשׁ חוֹלְקִין (תשב״ץ) וְטוֹב לְטוֹבְלוֹ בְּלֹא בְּרָכָה הַבַּרְזֶלִים שֶׁמְּתַקְּנִים בָּהֶם הַמַּצּוֹת אֵינָם צְרִיכִים טְבִילָה (אָרוֹךְ) וְכֵן כִּיסּוּי שֶׁכּוֹפִין עַל הַפַּת לֶאֱפוֹתוֹ אֲבָל כִּיסּוּי קְדֵירָה צָרִיךְ טְבִילָה (הַגָּהוֹת אשיר״י):
A sheḥita knife — and likewise the flaying knife — : one opinion (יש מי שאומר) holds that it requires no immersion. Rama's gloss: others disagree; it is good to immerse it without a blessing. The irons used to shape matzot require no immersion, nor does the cover placed over bread while baking; a pot lid, however, does require immersion.
The Mehaber's logic: the sheḥita knife acts before the food is food — the slaughtered animal still needs salting and cooking. So it is not a “mealtime vessel”. The Rama, cautious, prefers to immerse it without a blessing — the classic resolution of doubt: perform the act, refrain from the blessing.

Seif 6 — A wooden vessel with iron hoops

כְּלִי עֵץ שֶׁיֵּשׁ לוֹ חִשּׁוּקִים שֶׁל בַּרְזֶל מִבַּחוּץ שֶׁמַּעֲמִידִים אוֹתוֹ אֵינוֹ טָעוּן טְבִילָה:
A wooden vessel with iron hoops on the outside that hold it together does not require immersion.
The principle of the מעמיד: iron that merely holds the vessel together does not turn it into a metal vessel, so long as it is on the outside and the use does not pass through it. We look at where the use passes, not at what holds the thing upright.

Seif 7 — Metal and wood combined: where does the vessel essentially lie?

כּוֹס שֶׁל כֶּסֶף מְחוּבָּר בִּכְלִי עֵץ צָרִיךְ טְבִילָה: הגה וְכֵן רֵחַיִים שֶׁל פִּלְפְּלִין שֶׁבְּתוֹךְ הָעֵץ יֵשׁ בַּרְזֶל קָבוּעַ שֶׁטּוֹחֲנִין בּוֹ צָרִיךְ טְבִילָה (מָרְדְּכַי) וְכֵן הַמַּשְׁפֵּכוֹת שֶׁל בַּרְזֶל אוֹ הַבַּרְזוֹת שֶׁל בַּרְזֶל וּשְׁאָר מַתָּכוֹת כּוּלָּן צְרִיכִים טְבִילָה (אָרוֹךְ) וְדַוְקָא שֶׁעִיקַּר הַכְּלִי הוּא שֶׁל מַתָּכוֹת אֲבָל אִם עִיקַּר הַכְּלִי הוּא שֶׁל עֵץ רַק שֶׁמְּעַט בַּרְזֶל קָבוּעַ בּוֹ הוֹאִיל וְאֶפְשָׁר לְהִשְׁתַּמֵּשׁ בּוֹ בְּלֹא הַבַּרְזֶל אֵין צָרִיךְ טְבִילָה אֲבָל כְּלִי הַמְתוּקָּן בִּיתֵדוֹת שֶׁל בַּרְזֶל וּבְלֹא הַיְתֵדוֹת לֹא הָיָה אֶפְשָׁר לְהִשְׁתַּמֵּשׁ בּוֹ וְהֵם מִבִּפְנִים צָרִיךְ טְבִילָה (כָּךְ מַשְׁמַע מב״י בְּשֵׁם הַגָּהוֹת מיימוני פי״ז):
A silver cup set into a wooden holder requires immersion. Rama's gloss: likewise a pepper mill whose fixed iron piece does the grinding; likewise funnels and spigots of iron or other metal. But only where the vessel is essentially metal: if it is essentially wood with a little iron fixed in it, since it can be used without that iron, no immersion is needed. But a vessel held together by iron pegs without which it would be unusable, and which are on the inside, does require immersion.
The richest seif of the siman: it gives the general rule for composite vessels. Two questions: (1) where does the vessel essentially lie — metal or wood? (2) can it be used without the metal part? If the metal is indispensable and lies on the inside, the vessel is treated as a metal vessel.

Group C — The mode of acquisition: purchase, loan, pledge, manufacture (seifim 8-11)

Seif 8 — Borrowing or renting: no acquisition, no immersion

הַשּׁוֹאֵל אוֹ שׂוֹכֵר כְּלִי מֵהָעוֹבֵד כּוֹכָבִים אֵינוֹ טָעוּן טְבִילָה אֲבָל אִם יִשְׂרָאֵל קְנָאוֹ מֵהָעוֹבֵד כּוֹכָבִים וְהִשְׁאִילוֹ לַחֲבֵירוֹ טָעוּן טְבִילָה שֶׁכְּבָר נִתְחַיֵּיב בְּיַד הָרִאשׁוֹן וְיֵשׁ מִי שֶׁאוֹמֵר שֶׁאִם לֹא לְקָחוֹ הָרִאשׁוֹן לְצוֹרֶךְ סְעוּדָה אֶלָּא לַחְתּוֹךְ קְלָפִים וְכַיּוֹצֵא בּוֹ אֵין צָרִיךְ לְהַטְבִּילוֹ: הגה אֲבָל הָרִאשׁוֹן אָסוּר לְהִשְׁתַּמֵּשׁ בּוֹ לְצָרְכֵי סְעוּדָה אֲפִילּוּ דֶּרֶךְ עֲרַאי בְּלֹא טְבִילָה אַף עַל פִּי שֶׁלְּקָחוֹ לְצוֹרֶךְ קְלָפִים (ד״ע ואו״ה) וְכֵן אִם קְנָאוֹ יִשְׂרָאֵל הַשֵּׁנִי מִן הָרִאשׁוֹן לְצוֹרֶךְ סְעוּדָה צָרִיךְ טְבִילָה גַּבֵּי הַשֵּׁנִי (בֵּית יוֹסֵף):
One who borrows or rents a vessel from a non-Jew need not immerse it. But if a Jew bought it and then lent it to his fellow, it does require immersion — for the obligation already arose in the first one's hands. One opinion adds: if the first did not acquire it for mealtime use, but to cut parchments or the like, he need not immerse it. Rama's gloss: yet that first owner may not use it for a meal, even occasionally (דרך עראי), without immersion; and if a second Jew buys it from him for mealtime use, that second one must immerse it.
The pivot of the whole siman: the obligation arises from acquisition, not from use. Borrowing or renting acquires nothing → no immersion. And once the obligation has arisen with the first buyer, it does not lapse as the vessel passes into other Jewish hands. The “parchments” discussion tests the same idea: does a purchase not aimed at the table generate the obligation?

Seif 9 — The pledge (משכון): everything depends on the lender's intent

מִשְׁכֵּן עוֹבֵד כּוֹכָבִים כְּלִי לְיִשְׂרָאֵל אִם נִרְאֶה בְּדַעַת הָעוֹבֵד כּוֹכָבִים שֶׁרוֹצֶה לְשַׁקְּעוֹ בְּיָדוֹ טָעוּן טְבִילָה וְאִם לָאו יַטְבִּילֶנּוּ בְּלֹא בְּרָכָה אוֹ יִקְנֶה כְּלִי אַחֵר וְיַטְבִּילֶנּוּ עִמּוֹ: (וְאִם לַבַּסּוֹף נִשְׁתַּקַּע בְּיָדוֹ יַחֲזוֹר וְיַטְבִּילֶנּוּ בְּלֹא בְּרָכָה) (בֵּית יוֹסֵף בְּשֵׁם תְּשׁוּבָה אַשְׁכְּנַזִית וְאָגוּר וְהוּא בִּתְשׁוּבַת מהרי״ל סִימָן ס׳):
A non-Jew pledged a vessel to a Jew (משכון): if it appears from his intent that he means to leave it permanently (לשקעו) in the Jew's handsimmersion required. If not → one immerses it without a blessing, or buys another vessel and immerses it together with it. Rama's gloss: and if in the end it does remain permanently in his hands, he immerses it again, without a blessing.
A halakha of intent: a pledge is an ambiguous status — the object is with the Jew but is not his. Everything turns on what the lender means. Hence the twofold remedy: immersion without a blessing, or immersing it together with a vessel that is clearly obligated, over which the blessing is genuinely due. This is a tool that recurs throughout the siman.

Seif 10 — The Jew supplies the metal, the non-Jewish craftsman forms it

יִשְׂרָאֵל שֶׁנָּתַן כֶּסֶף לְאוּמָּן עוֹבֵד כּוֹכָבִים לַעֲשׂוֹת לוֹ מִמֶּנּוּ כְּלִי אֵינוֹ צָרִיךְ טְבִילָה (כֵּן מַשְׁמַע מִמָּרְדְּכַי): הגה וְיֵשׁ חוֹלְקִין (טוּר בְּשֵׁם ריצב״א) וְיֵשׁ לְטוֹבְלוֹ בְּלֹא בְּרָכָה וְאִם מִקְצָת הַכֶּסֶף שֶׁנַּעֲשָׂה מִמֶּנּוּ הַכְּלִי שֶׁל עוֹבֵד כּוֹכָבִים צָרִיךְ טְבִילָה (מַשְׁמַע מִמָּרְדְּכַי) וְכֵן אוּמָּן יִשְׂרָאֵל שֶׁעָשָׂה כְּלִי לְעוֹבֵד כּוֹכָבִים וּקְנָאוֹ מִמֶּנּוּ יַטְבִּילֶנּוּ גַּם כֵּן בְּלֹא בְּרָכָה אִם הָעוֹבֵד כּוֹכָבִים נָתַן כָּל הַמַּתָּכוֹת (אָרוֹךְ) אֲבָל אִם עֲשָׂאוֹ לְעַצְמוֹ רַק שֶׁקָּנָה הַמַּתָּכוֹת מִן הָעוֹבֵד כּוֹכָבִים אוֹ שֶׁנָּתַן מִקְצָת מַתָּכוֹת מִשֶּׁלּוֹ אֵין צָרִיךְ טְבִילָה (ב״י בְּשֵׁם הַגָּהוֹת אשיר״י):
A Jew who gave his own metal to a non-Jewish craftsman to fashion a vessel from it → no immersion. Rama's gloss: others disagree; it should be immersed without a blessing. If part of the metal belonged to the non-Jewimmersion required. Likewise a Jewish craftsman who made a vessel for a non-Jew and then bought it back from him: he immerses it without a blessing, if all the metal came from the non-Jew. But if he made it for himself, having merely bought the metal from the non-Jew, or if he contributed part of the metalno immersion.
The underlying question: what in the vessel “belongs” to the non-Jew — the material or the workmanship? The Mehaber answers: the material; the craftsman acquired nothing, hence no immersion. The Rama brings the opposing view (the craftsman acquires through his workmanship) and rules by the familiar compromise: immerse without a blessing.

Seif 11 — Selling and buying back; theft and confiscation

יִשְׂרָאֵל שֶׁמָּכַר כְּלִי לְעוֹבֵד כּוֹכָבִים וְחָזַר וּלְקָחוֹ מִמֶּנּוּ צָרִיךְ טְבִילָה אֲבָל אִם מִשְׁכְּנוֹ בְּיָדוֹ וְחָזַר וּפְדָאוֹ מִמֶּנּוּ אֵינוֹ צָרִיךְ טְבִילָה: הגה יִשְׂרָאֵל וְעוֹבֵד כּוֹכָבִים שֶׁקְּנָאוֹ כְּלִי בְּשׁוּתָּפוּת אֵין צָרִיךְ טְבִילָה יִשְׂרָאֵל שֶׁגְּנָבוֹ אוֹ גְּזָלוֹ מִמֶּנּוּ כֵּלָיו וְהוּחְזְרוּ לוֹ אֵין צָרִיךְ טְבִילָה אֲבָל שַׂר אוֹ מוֹשֵׁל שֶׁאָנְסוּ יִשְׂרָאֵל וְלָקְחוּ כֵּלָיו וְהוּחְזְרוּ לוֹ צְרִיכִין טְבִילָה דִּכְבָר נִשְׁתַּקְּעוּ בְּיַד הָעוֹבֵד כּוֹכָבִים (אָרוֹךְ):
A Jew who sold a vessel to a non-Jew and then bought it backimmersion required. But if he had only pledged it to him and later redeemed itno immersion. Rama's gloss: a vessel bought in partnership (בשותפות) by a Jew and a non-Jew → no immersion. Vessels stolen or robbed from a Jew and returned to him → no immersion; but if a lord or governor seized them by force and they were returned → immersion required, for they had already passed permanently (נשתקעו) into the non-Jew's hands.
Two regimes of transfer: a sale removes the vessel from Israel's domain — buying it back is acquiring from a non-Jew. A pledge does not: the vessel remains Jewish and is merely redeemed. The Rama applies the same measure to theft: a thief cannot display his spoil, so the vessel does not “bear the non-Jew's name”; a ruler who confiscates openly does.

Group D — Performing the immersion and the after-the-fact remedies (seifim 12-16)

Seif 12 — The handles (ידות)

צָרִיךְ לְהַטְבִּיל יְדֵי הַכְּלִי:
One must immerse the handles of the vessel (ידי הכלי) as well.
A two-word seif, and a decisive one: the vessel is immersed in its entirety. Handles and grips are part of the vessel, not something beside it. This is also the practical reason behind seif 2: the water must reach everything, including what the hand covers.

Seif 13 — Rust: when does it constitute a חציצה?

צָרִיךְ לְהַעֲבִיר הֶחֲלוּדָה קוֹדֶם טְבִילָה וְאִם לֹא הֶעֱבִיר אִם מַקְפִּיד עָלָיו חוֹצֵץ וְאִם שִׁפְשֵׁף וְנָתַן בְּגֶחָלִים וְנִשְׁאַר עֲדַיִין מְעַט שֶׁל חֲלוּדָה שֶׁלֹּא יָכוֹל לַעֲבוֹר עַל יְדֵי כָּךְ הָוֵי מִיעוּטוֹ שֶׁאֵינוֹ מַקְפִּיד עָלָיו וְאֵינוֹ חוֹצֵץ (וע״ל סִימָן ר״ב מִדִּין חֲצִיצָה):
One must remove the rust before immersion. If one did not: if one is particular about it (מקפיד), it interposes. But if one scoured it and put it in coals and a little rust remains that cannot be removed that way, it is a “small remainder one is not particular about” (מיעוטו שאינו מקפיד): it does not interpose. (The Mehaber himself refers onward to the laws of חציצה.)
The general rule of חציצה, in miniature: what blocks is not the foreign matter itself but how one regards it. What bothers a person (מקפיד) interposes; what one tolerates, over a minor portion, does not. Hence the concrete step: clean first, and worry only about the residue that resists.

Seif 14 — A minor is not believed about the immersion

אֵין מַאֲמִינִים קָטָן עַל טְבִילַת כֵּלִים. (אֲבָל אִם טָבְלוּ לִפְנֵי גָּדוֹל הָוֵי טְבִילָה) (ת״ה סִימָן רנ״ז):
A minor (קטן) is not believed when he says he immersed the vessels. Rama's gloss: but if he immersed them in the presence of an adult, the immersion is valid.
A question of נאמנות: immersion is a fact that cannot be checked afterwards — an immersed vessel looks no different from a dry one. Testimony therefore decides, and a minor is not a witness. But the Rama keeps the two planes apart: performing the immersion and attesting that it was performed.

Seif 15 — An immersion carried out by a non-Jew

אִם הִטְבִּיל כֵּלִים עַל יְדֵי עוֹבֵד כּוֹכָבִים עָלְתָה לָהֶם טְבִילָה. (אֲבָל אֵינוֹ נֶאֱמָן עַל הַטְּבִילָה) (ד״ע):
If one had the vessels immersed by a non-Jew, the immersion counts for them. Rama's gloss: but he is not believed when he claims to have done it.
The same distinction, applied to a non-Jew: his act works — the immersion is valid — but his word does not. Read seifim 14 and 15 together: in both, the obstacle is not the capacity to act but the reliability of the report.

Seif 16 — Forgotten before Shabbat: the gift to a non-Jew

אִם שָׁכַח וְלֹא הִטְבִּיל כְּלִי מֵעֶרֶב שַׁבָּת אוֹ מֵעֶרֶב יוֹם טוֹב יִתְּנֶנּוּ לְעוֹבֵד כּוֹכָבִים בְּמַתָּנָה וְאַחַר כָּךְ יִשְׁאָלֶנּוּ מִמֶּנּוּ וּמוּתָּר לְהִשְׁתַּמֵּשׁ בּוֹ: הגה וְכֵן יַעֲשֶׂה אֲפִילּוּ בְּחוֹל בְּמָקוֹם שֶׁאֵין לוֹ מִקְוֶה (ב״י) וְאִם עָבַר וְהִשְׁתַּמֵּשׁ בַּכְּלִי בְּלֹא טְבִילָה לֹא נֶאֱסַר מַה שֶּׁנִּשְׁתַּמֵּשׁ בּוֹ וְיַטְבְּלֶנּוּ עוֹד: (טוּר וְהַפּוֹסְקִים):
If one forgot to immerse a vessel before Shabbat or before a yom tov: one gives it to a non-Jew as a gift and then borrows it back from him — and it is permitted to use it. Rama's gloss: one does the same on a weekday where no mikveh is available. And if one transgressed and used the vessel without immersion, what was prepared in it is not forbidden — and one immerses the vessel afterwards.
The emergency exit: one may not immerse a vessel on Shabbat, and an un-immersed vessel may not be used. The Shulchan Aruch therefore proposes changing the ownership: the vessel belongs to the non-Jew and the Jew merely borrows it — and a borrowed vessel needs no immersion (seif 8). The Rama adds the reassuring news: wrongful use does not forbid the food.

2. Background — where the mitzva of טבילת כלים comes from

The starting point is a verse in the book of Bamidbar, on the return from the war against Midian. A spoil of metal vessels is brought into the camp, and Elazar the Kohen teaches how to make them usable:

כָּל דָּבָר אֲשֶׁר יָבֹא בָאֵשׁ תַּעֲבִירוּ בָאֵשׁ וְטָהֵר

— Bamidbar 31:23

Two distinct acts appear in this verse: passing through fire (this will be hag‘ala and libbun, the subject of Siman 121) and an “and it shall be pure” (וְטָהֵר) that comes afterwards. It is that extra word which the Sages read as the obligation of immersion. The Rambam states it plainly: this immersion has nothing to do with ritual tum’a, and the verse is only a remez — the obligation itself being mi-divrei sofrim (Rambam, Hilkhot Ma’akhalot Assurot, chapter 17, halakha 5). Other Rishonim hold it to be a Torah obligation; the Taz writes bluntly:

לפי שטבילת כלים דאורייתא

— ט״ז יו״ד ק״כ ס״ק ט״ז

The siman’s major questions

  1. What is immersed? Not every vessel: only mealtime vessels (כלי סעודה), and only in certain materials.
  2. Why, if the vessel is new? Because immersion removes no dirt and expels no taste: it marks a change of domain.
  3. When does the obligation arise? Upon acquisition — hence the whole run of seifim 8 to 11 on borrowing, renting, pledging and commissioning.
  4. What is done in doubt? The Rama’s constant answer: immerse without a blessing, or immerse the doubtful vessel together with one that is certainly obligated.
Immersing vessels is neither cleaning nor kashering (הכשר כלים, the subject of Siman 121). A vessel used for non-kosher food while hot will need both: kashering first, then immersion. A brand-new vessel straight from the factory will need only immersion.

3. The key concepts of this siman

כְּלֵי סְעוּדָה — mealtime vessels. Only vessels serving the table are at issue. The Rambam already says that they obligated in this immersion only metal mealtime vessels acquired from a non-Jew (Hilkhot Ma’akhalot Assurot 17:6). Hence the standing of the trivet (seif 4) and the sheḥita knife (seif 5): they serve around the meal, not at it.
מַתָּכוֹת וּזְכוּכִית — metal and glass. Metal is explicit in the verse. Glass is assimilated to it, the Taz explains, because it is repairable by melting down (ט״ז יו״ד ק״כ ס״ק א): once broken, it can become again what it was — just like metal. Bare wood, stone and earthenware are exempt.
מְצוּפִּים בַּאֲבָר — the tin lining. An earthenware vessel lined with tin on the inside is treated as metal, since it is the metal that meets the food. The Mehaber therefore obligates immersion; the Rama brings the view that the lining is there only for appearance, and concludes: immerse without a blessing, and such is the custom.
אַרְבָּעִים סְאָה — the forty se’ah. The immersion takes place in a mikveh or a spring holding the ordinary measure of forty se’ah. In other words: this is not a rinse but a genuine immersion, governed by the laws of mikvaot.
חֲצִיצָה — interposition. Anything that comes between the water and the vessel invalidates the immersion. Two applications here: the gripping hand (seif 2) and rust (seif 13). The decisive test is הקפדה — whether or not one is particular about that residue.
יְדוֹת הַכְּלִי — the handles. They are part of the vessel and must be immersed as well (seif 12). This also explains the difficulty of seif 2: the holding hand covers precisely a part the water must reach.
עִיקַּר הַכְּלִי / מַעֲמִיד — the essence and the support. For a composite vessel, one does not ask what it is made of but where the use passes. An external iron hoop merely holds (מעמיד) and does not obligate (seif 6). An internal metal part, indispensable to the use, does obligate (seif 7).
נִשְׁתַּקַּע בְּיַד הָעוֹבֵד כּוֹכָבִים — “it settled permanently in his hands”. This is the criterion that separates pledge, sale and theft (seifim 9 and 11). So long as the non-Jew does not truly hold the vessel — a thief who must hide it, a lender awaiting repayment — the vessel does not “bear his name”, and no obligation arises.
טְבִילָה בְּלֹא בְּרָכָה — immersing without a blessing. A tool for resolving doubts that runs through the whole siman: one performs the act, whose omission would be serious, and refrains from the blessing, whose recitation in vain would be serious too. A variant appears in seif 9: immerse the doubtful vessel together with one that is certainly obligated, over which the blessing is genuinely due.

4. Materials and blessing — the summary table

The siman never answers with a bare “yes / no”: it answers in two columns, is immersion required? and is the blessing recited? Here is what seifim 1 to 7 and seif 10 yield.

Read from top to bottom, the “blessing” column tells the story of the siman by itself: wherever a maḥloket remains, the blessing falls away and the immersion stays. That is the Rama’s signature in this chapter.

5. The Taz and the Shach — two key entries

The two great commentaries printed around the Shulchan Aruch on Yoreh De‘ah are the Taz (Turei Zahav, Rabbi David haLevi Segal, 1586-1667) and the Shach (Siftei Kohen, Rabbi Shabtai haCohen, 1621-1662). On this siman each opens a different door.

A key entry from the Taz

Taz s.k. 1 — why glass, and what immersion is for

וזכוכית גם כן יש לו דין מתכות כיון שאם נשבר יש לו תקנה בהיתוך. וטעם הטבילה כדי שיצאו מטומאתו של עובד כוכבים לקדושתו של ישראל

— ט״ז יו״ד ק״כ ס״ק א

Glass, too, has the status of metal, since if it breaks it can be restored by melting down. And the reason for the immersion is that they may pass out of the non-Jew’s impurity into the holiness of Israel.
Two ideas in a single line. First a technical criterion: what brings glass close to metal is its reversibility. Then the underlying reason for the whole siman: immersion is a passage between domains, not a cleaning. This sentence explains at a stroke why a brand-new vessel is included, and why a borrowed one is not.

A key entry from the Shach

Shach s.k. 8 — the wording of the blessing

ויש פוסקים לברך על טבילת כלי מתכות וכ״כ הב״ח שכן עיקר ושכן ראה נוהג ע״פ זקנים

— ש״ך יו״ד ק״כ ס״ק ח

Some decisors have one recite “on the immersion of metal vessels”; so writes the Baḥ, for whom this is the primary view, and who reports having seen it practised on the authority of the elders.
The Mehaber had fixed עַל טְבִילַת כְּלִי / כֵּלִים (seif 3). The Shach notes that another practice exists, more explicit. The Taz, in the same place, opposes it and concludes that nothing should be changed from the custom. Here, in miniature, is how the wording of a blessing settles: through a back-and-forth between reasoning and received practice.

6. The Rama’s gloss (הגה) — the “without a blessing” line

The Rama intervenes in nine of the sixteen seifim. Taken together, his glosses form a coherent teaching, worth reading as a whole.

On seif 1 — the tin lining

The Mehaber obligates immersion with a blessing; the Rama brings the opposing view and concludes with וְכֵן נוֹהֲגִיןand such is the custom. The first appearance of the formula that shapes the entire chapter.

On seif 5 — the sheḥita knife

Where the Mehaber exempts, the Rama writes וְטוֹב לְטוֹבְלוֹ בְּלֹא בְּרָכָה: immersion as a precaution, the blessing as a risk to be avoided.

On seif 7 — composite vessels

This is the longest gloss in the siman and the most useful: it supplies the general rule — where the vessel essentially lies, whether it can be used without the metal part, and where that part sits (inside or outside).

On seifim 8, 9, 10 and 11 — the mode of acquisition

Four consecutive glosses sharpen the same question: did the vessel truly pass through the non-Jew’s domain? The Rama adds the case of partnership (שותפות), that of theft, and that of confiscation by a ruler — three ways of testing the very same boundary.

On seifim 14, 15 and 16 — trustworthiness and remedy

A minor who immersed in the presence of an adult has made a valid immersion; a non-Jew who immerses makes a valid immersion but is not believed; and one who used the vessel without immersion has not rendered the food forbidden. Three ways of saying that the mistake can be repaired.

A single line runs through these nine glosses: the immersion is never given up, the blessing is. It is the application of a broad halakhic principle — safek berakhot lehakel, in doubt one refrains from blessing — carried through a single chapter with remarkable consistency.

7. Practical cases today

Case 1 — Dishes and cutlery bought in a store

Glass plates, steel cutlery, saucepans: the central case of seif 1. Mealtime vessels, a qualifying material, purchased from a non-Jewish seller → immersion with a blessing. The fact that they are new and boxed changes nothing: that is precisely what seif 1 takes the trouble to state (אַף עַל פִּי שֶׁהֵם חֲדָשִׁים). One must, however, remove labels and glue residue before immersing — a direct application of seif 13.

Case 2 — Tableware rented for a simḥa

A caterer rents vessels from a non-Jewish company for a wedding. Seif 8 is explicit: שוכר — a renter acquires nothing, and the vessel requires no immersion. But note the reversal within the same seif: if the renter-out is a Jew who bought the stock from a non-Jew, the obligation already arose in his hands, and the ware should have been immersed.

Case 3 — Electrical appliances and composite vessels

A kettle, a mixer, a sandwich press: these are exactly the composite vessels of seif 7. The two questions to ask are the Rama’s — where does the vessel essentially lie, and can it be used without its metal part? Since considerations peculiar to electricity (damage, danger, disassembly) go beyond the seif’s frame, such cases are put to a Rav before anything is immersed.

Case 4 — Rust, labels, glue residue

Seif 13 supplies both the rule and the action. The rule: whatever one is particular about (מקפיד) constitutes a חציצה. The action: clean first, and only then consider the residue that resists — which, if it is a tolerated minority, does not invalidate the immersion.

Case 5 — Realising it on Friday night

The serving dish was never immersed and Shabbat has begun: it can no longer be immersed. The remedy of seif 16 is strikingly elegant — give it to a non-Jew as a gift, then borrow it back. The vessel no longer being ours, it falls under seif 8: a borrowed vessel needs no immersion. And if it has already been used without immersion, the Rama reassures: the food is not forbidden — the vessel will be immersed after Shabbat.

8. Summary of Siman 120

In one sentence: a mealtime vessel of metal or glass acquired from a non-Jew must be immersed in a mikveh of forty se’ah with a blessing before any use — and the sixteen seifim do nothing but define the four emphasised terms: mealtime vessel, metal or glass, acquired, with a blessing.

Comprehension questions

  1. Why does a brand-new vessel, never used, still require immersion? Which sentence of the Taz answers this?
  2. A trivet and a baking plate are both of metal. Why is one exempt and the other not?
  3. What is the difference between the external iron hoops of seif 6 and the internal iron pegs of seif 7?
  4. A Jew rents tableware from a non-Jewish company: immersion or not? And if the renter-out is a Jew who bought his stock from a non-Jew?
  5. Why does buying back after a sale require immersion, while redeeming after a pledge does not?
  6. Seif 14 refuses to believe a minor; seif 15 accepts an immersion performed by a non-Jew. Do these two seifim contradict each other? What distinction reconciles them?
