✦ ❖ ✦
After teaching the respect due to the tefilin (siman 40) and the writing of the letters of the Name, the Shulchan Aroukh here teaches whether one may transform a tefilin. One does not make of a של ראש a של יד — not even to take a רצועה from it — because one does not downgrade from a קדושה חמורה to a קדושה קלה; and the של ראש has the heaviest holiness, for the essence of the Name שד״י is upon it. From של יד to של ראש: permitted (seif 1). One who set a condition (התנה) at the outset may transform them even from של ראש to של יד (seif 2). Finally, the הזמנה: a סודר designated and used once for tefilin becomes forbidden for profane use; and the קלף מעובד לשם תפילין may not receive profane writing (seif 3). Hebrew text, fluent English translation and explanations of the three seifim, with a section of practical cases.

The tefilin are תשמישי קדושה — objects of sanctity — and they are not all of one degree: the של ראש, upon which the essence of the Name שד״י is found, surpasses the של יד in holiness. From this principle follows a rule of conduct: one may elevate toward a higher holiness, but one does not downgrade toward a lesser one (מעלין בקודש ואין מורידין). The siman applies this to the שינוי — the transformation of a tefilin — then to the הזמנה, the mere designation of an object for holiness. We study here at the level of principle; for personal conduct, one refers to the ruling of the Rav.

A. אין מורידין מקדושה חמורה לקלה — transforming a tefilin (seif 1)
Original text (seif 1)
[א] אסור לשנות תפילין של ראש לעשותן של יד, ואפילו ליקח רצועה מהם וליתן בשל יד — אסור, מפני שאין מורידין מקדושה חמורה לקדושה קלה; ושל ראש קדושתו חמורה, שרובו של שד״י בשל ראש. אבל משל יד לשל ראש — מותר לשנות. ואם היו חדשים שעדיין לא הניחם — מותר לשנות אפילו משל ראש לשל יד, שטולה עליהם מכסה עור אחד ונראים כבית אחד.
[1] It is forbidden to transform a tefilin of the head (של ראש) in order to make of it a tefilin of the arm (של יד) — and even to take a strap (רצועה) from it and put it on the של יד, it is forbidden — because one does not downgrade from a heavier holiness (קדושה חמורה) to a lighter one (קדושה קלה); and the של ראש, its holiness is heavier, for the essence of the Name שד״י is on the של ראש. But from של יד to של ראש — it is permitted to transform. And if they were new (חדשים), not yet worn — it is permitted to transform even from של ראש to של יד, by placing upon them a single leather cover (מכסה עור), so that they appear as a single box (בית אחד).
אֵין מוֹרִידִין מִקְּדֻשָּׁה חֲמוּרָה לִקְדֻשָּׁה קַלָּה — “one does not downgrade from a heavier holiness to a lighter one” — a general principle of the תשמישי קדושה: a consecrated object may be elevated toward a higher holiness, but not lowered toward a lesser one (מעלין בקודש ואין מורידין). Since the של ראש is holier than the של יד, to make it into a של יד would be to downgrade it — hence forbidden, even for a single רצועה taken from one and given to the other.
רֻבּוֹ שֶׁל שד״י — “the essence of the Name שד״י” — why is the של ראש holier? Because the greater part of the divine Name שד״י is upon it: the שי״ן is formed on the box of the של ראש and the ד׳ in its knot (קשר), whereas the של יד carries only the יו״ד of its knot. The של ראש is “worth more”: hence the prohibition against downgrading it.
חֲדָשִׁים שֶׁלֹּא הֱנִיחָן — “new ones not yet worn” — tefilin that are new, never worn, have not yet received the full holiness of use; one may therefore transform them even from של ראש to של יד. To do so, one places upon them a single leather cover (מכסה עור), so that the four compartments appear, on the outside, as a single box — as befits a של יד.
What this seif says:
- The prohibition: not to make a של יד from a של ראש, even to take a רצועה.
- The reason: אין מורידין — one does not downgrade from a קדושה חמורה to a קדושה קלה.
- Why: the של ראש is holier, for רובו של שד״י is upon it.
- The permission: from של יד to של ראש; and for חדשים, even the reverse, with a מכסה עור.
The seif in one sentence: one does not downgrade the holiness of a tefilin — from של ראש (holier, for רובו של שד״י) to של יד is forbidden, even a רצועה; from של יד to של ראש is permitted; and new ones never worn may even be transformed into a של יד with a מכסה עור.
B. תנאי · הזמנה — the condition set at the outset (seif 2)
Original text (seif 2)
[ב] אם התנה עליהם מתחילה, אפילו לבשן אדם — יכול לשנותן, אפילו משל ראש לשל יד.
[2] If he set a condition (התנה) upon them at the outset, even after a man has worn them — he may transform them, even from של ראש to של יד.
תְּנַאי · הַזְמָנָה — “the condition” · “the designation” — in seif 1, transforming the של ראש into a של יד was forbidden because its full holiness had settled upon it. But one who, at the outset, set a condition (התנה מתחילה) — reserving the right to transform them — did not let that holiness settle irrevocably. Therefore, even after wearing them, he may transform them, even from של ראש to של יד.
What this seif says:
- The principle: a condition set at the outset (מתחילה) changes the rule of seif 1.
- The scope: even after having worn them (לבשן), he may transform them.
- How far: even from של ראש to של יד — which was forbidden without a condition.
The seif in one sentence: one who set a condition at the outset may transform his tefilin even from של ראש to של יד, and even after wearing them — for the condition prevents the holiness from settling irrevocably.
C. הזמנה מילתא היא — the סודר and the קלף (seif 3)
Original text (seif 3)
[ג] סודר דאזמניה למיצר ביה תפילין לעולם, וצר ביה תפילין חד זמנא — אסור למיצר ביה זוזי. הגה: ואם התנה עליו מתחילה, בכל ענין שרי (ב״י בשם רבינו ירוחם ומהרי״א). וקלף המעובד לשם תפילין — אסור לכתוב עליו דברי חול, דהזמנה כי האי גוונא לגוף הקדושה מילתא היא (ר״ן ס״פ נגמר הדין). אזמניה ולא צר ביה, או צר ביה ולא אזמניה — שרי למיצר ביה זוזי.
[3] A cloth (סודר) that one designated (אזמניה) to wrap tefilin in permanently (לעולם), and in which one actually wrapped tefilin once (חד זמנא) — it is forbidden to wrap coins (זוזי) in it. Rama: and if he set a condition upon it at the outset, in any case it is permitted (Beit Yossef in the name of Rabbeinou Yeruḥam and the Mahari Abouhav). And a parchment processed for the sake of tefilin (קלף מעובד לשם תפילין) — it is forbidden to write profane things (דברי חול) upon it, for a designation of this kind, for the body of holiness (גוף הקדושה), is a real thing (מילתא היא) (Ran, end of chapter נגמר הדין). Designated it but did not wrap in it, or wrapped in it but did not designate it — it is permitted to wrap coins in it.
הַזְמָנָה מִילְתָא הִיא — “designation is a real thing” — the הזמנה is the act of destining an object to holiness. For the תשמישי קדושה (such as the סודר), designation alone does not suffice: one must both have designated it forever and used it once (אזמניה וצר). Then the object becomes holy, and it is forbidden to put coins (זוזי) in it. But if the two are not joined — designated without use, or use without designation — it is permitted.
קְלָף מְעֻבָּד לְשֵׁם תְּפִלִּין · גּוּף הַקְּדֻשָּׁה — “the parchment processed for the sake of tefilin” · “the body of holiness” — the parchment prepared in order to write tefilin upon it touches the very body of holiness (not a mere accessory). For it, designation alone is already effective (מילתא היא): it is therefore forbidden to write profane things upon it, even before anything has been written.
וְאִם הִתְנָה — “and if he set a condition” (Rama) — as in seif 2, a condition set at the outset defuses the prohibition: one who, in designating his סודר, reserved the right to put coins in it as well, may do so “in any case” (בכל ענין). The condition accompanies the whole sougya of the שינוי and the הזמנה.
What this seif says:
- The סודר: designated forever and used once → forbidden to put זוזי in it.
- The תנאי: a condition at the outset permits everything (Rama, in the name of Rabbeinou Yeruḥam and the Mahari Abouhav).
- The קלף לשם תפילין: designation alone suffices — forbidden to write דברי חול upon it (Ran).
- Both are needed: designated without use, or use without designation → permitted.
The seif in one sentence: the הזמנה is effective — a סודר designated and used once for tefilin becomes forbidden for coins (except with a condition set at the outset), and the קלף מעובד לשם תפילין may not receive profane writing; but for the סודר, one must join designation and use.
Practical cases
Case 1 — Reusing a strap or a box of the של ראש
Situation: someone has a של ראש he no longer uses, and would like to take a רצועה — or the box — for his של יד.
Conduct: it is forbidden. One does not make a של יד from a של ראש, and even to take a רצועה from one and give it to the other is forbidden (seif 1). The reason is אין מורידין מקדושה חמורה לקדושה קלה: since the של ראש is holier, using it for the של יד would downgrade it. The reverse — from של יד to של ראש — would be permitted, since that is to elevate. In practice, one does not recycle the parts of the של ראש into the של יד, and one asks the Rav about the genizah of pieces no longer needed.
Case 2 — The tefilin bag and the condition
Situation: someone has a סודר (or a bag) he uses for his tefilin. May he also keep money or other profane objects in it?
Conduct: everything depends on the הזמנה. If he designated it forever for the tefilin and actually wrapped tefilin in it, the cloth has become holy: forbidden to put זוזי in it (seif 3). But if he only designated without using, or used without designating, it is permitted. And above all, one who set a condition at the outset — reserving the right to put profane things in it as well — may do so “in any case” (Rama). In practice, many set such a condition; on this point one follows the custom and the Rav's opinion.
Case 3 — Why the של ראש “is worth more”
Situation: someone wonders: the two tefilin contain the same parchments; why would the של ראש be holier than the של יד?
Conduct: the של ראש bears the greater part of the Name שד״י: the שי״ן on its box and the ד׳ in its knot (קשר), whereas the של יד carries only the יו״ד. Its holiness is therefore heavier (קדושה חמורה), and this is why one may not downgrade it into a של יד — whereas the reverse, which would elevate it, is permitted (seif 1). For the detail of the shitot, one refers to the Lamdan level and to the ruling of the Rav.
