אָתְיָא בְּקַל וָחוֹמֶר מִנּוֹצָה שֶׁל עִזִּים שֶׁאֵין מִטַּמֵּא בִּנְגָעִים – מִטַּמֵּא בְּאֹהֶל הַמֵּת, עוֹר בְּהֵמָה טְמֵאָה שֶׁמִּטַּמְּאָה בִּנְגָעִים – אֵינוֹ דִּין שֶׁמִּטַּמְּאָה בְּאֹהֶל הַמֵּת.

It is derived through an a fortiori inference from goats’ hair. Although goats’ hair does not become ritually impure from leprosy, it does become ritually impure as a tent over a corpse; with regard to the hide of a non-kosher animal that becomes ritually impure from leprosy, is it not the case that it becomes ritually impure as a tent over a corpse?

וְאֶלָּא הָא דְּתָנֵי רַב יוֹסֵף: לֹא הוּכְשְׁרוּ בִּמְלֶאכֶת שָׁמַיִם אֶלָּא עוֹר בְּהֵמָה טְהוֹרָה בִּלְבַד, לְמַאי הִלְכְתָא? לִתְפִילִּין. תְּפִילִּין?! בְּהֶדְיָא כְּתִיב בְּהוּ: “לְמַעַן תִּהְיֶה תּוֹרַת ה׳ בְּפִיךָ״ – מִן הַמּוּתָר בְּפִיךָ.

Since the conclusion was that the hide of even a non-kosher animal can become ritually impure as a tent over a corpse, it is not necessary to assume that the covering of the Tabernacle was made specifically from the hide of a kosher animal. And, if so, that which Rav Yosef taught: Only the hide of a kosher animal was suitable for heavenly service, for what halakha halakha was stated with regard to phylacteries, Phylacteries? Why did Rav Yosef need to state that halakha ? It is written explicitly with regard to them: “And it shall be for a sign unto you upon your hand, and for a memorial between your eyes, that the law of the Lord may be in your mouth” (Exodus 13:9). The Sages derived from there that the phylacteries must be prepared from that which is permitted to be eaten in your mouth.

אֶלָּא לְעוֹרָן. וְהָאָמַר אַבַּיֵי: שי״ן שֶׁל תְּפִילִּין הֲלָכָה לְמֹשֶׁה מִסִּינַי!

Rather, the Gemara explains that this halakha of Rav Yosef was said only with regard to the leather of the boxes that house the phylacteries, which must be crafted from the hide of a kosher animal. It was not referring to the parchment on which the portions of the Torah inserted into the phylacteries are written. The Gemara asks: Didn’t Abaye say: The obligation to make a letter shin protruding on the phylacteries of one’s head is a halakha transmitted to Moses from Sinai? Since Torah law addresses the boxes of the phylacteries, presumably their legal status is parallel to that of the parchment and the prohibition against preparing them from the hide of a non-kosher animal is by Torah law as well.

אֶלָּא לְכוֹרְכָן בִּשְׂעָרָן וּלְתוֹפְרָן בְּגִידָן. הָא נַמִי הֲלָכָה לְמֹשֶׁה מִסִּינַי הוּא, דְּתַנְיָא: תְּפִילִּין מְרוּבָּעוֹת הֲלָכָה לְמֹשֶׁה מִסִּינַי, נִכְרָכוֹת בִּשְׂעָרָן וְנִתְפָּרוֹת בְּגִידָן.

Rather, the Gemara explains that Rav Yosef’s halakha comes to teach that one must tie the parchments upon which the portions of the Torah are written in the phylacteries with a kosher animal’s hair, as well as sew the phylacteries with a kosher animal’s sinews. The Gemara asks: The source of these halakhot is also a halakha transmitted to Moses from Sinai, as it was taught in a baraita : The requirement that phylacteries must be square is a halakha transmitted to Moses from Sinai, as is the requirement that they must be tied with their hair and sewn with their sinews.

אֶלָּא לִרְצוּעוֹת. וְהָאָמַר רַבִּי יִצְחָק: רְצוּעוֹת שְׁחוֹרוֹת הֲלָכָה לְמֹשֶׁה מִסִּינַי. נְהִי דִּגְמִירִי שְׁחוֹרוֹת – טְהוֹרוֹת מִי גְּמִירִי?

Rather, the Gemara says that Rav Yosef came to teach with regard to the halakha of the straps of the phylacteries. The Gemara asks: Didn’t Rabbi Yitzḥak say: The straps of the phylacteries must be black is a halakha transmitted to Moses from Sinai? The Gemara responds: Although we learned this halakha , which states that the straps must be black, did we also learn that they must be from kosher animals? Rav Yosef was certainly referring to straps when he said that all heavenly service must be performed with the hides of kosher animals.

מַאי הָוֵי עֲלָהּ דְּתַחַשׁ שֶׁהָיָה בִּימֵי מֹשֶׁה? אָמַר רַבִּי אֶלְעָא אָמַר רַבִּי שִׁמְעוֹן בֶּן לָקִישׁ, אוֹמֵר הָיָה רַבִּי מֵאִיר : תַּחַשׁ שֶׁהָיָה בִּימֵי מֹשֶׁה בְּרִיָּה בִּפְנֵי עַצְמָהּ הָיָה, וְלֹא הִכְרִיעוּ בָּהּ חֲכָמִים אִם מִין חַיָּה הוּא אִם מִין בְּהֵמָה הוּא, וְקֶרֶן אַחַת הָיְתָה לוֹ בְּמִצְחוֹ, וּלְפִי שָׁעָה נִזְדַּמֵּן לוֹ לְמֹשֶׁה, וְעָשָׂה מִמֶּנּוּ מִשְׁכָּן וְנִגְנַז.

The Gemara asks: What is the halakhic conclusion reached about this matter of the taḥash that existed in the days of Moses? Rabbi Ela said that Rabbi Shimon ben Lakish said that Rabbi Meir used to say: The taḥash that existed in the days of Moses was a creature unto itself, and the Sages did not determine whether it was a type of undomesticated animal or a type of domesticated animal. And it had a single horn on its forehead, and this taḥash happened to come to Moses for the moment while the Tabernacle was being built, and he made the covering for the Tabernacle from it. And from then on the taḥash was suppressed and is no longer found.

מִדְּקָאָמַר קֶרֶן אַחַת הָיְתָה לוֹ בְּמִצְחוֹ – שְׁמַע מִינָּהּ טָהוֹר הָיָה, דְּאָמַר רַב יְהוּדָה: שׁוֹר שֶׁהִקְרִיב אָדָם הָרִאשׁוֹן קֶרֶן אַחַת הָיְתָה לוֹ בְּמִצְחוֹ, שֶׁנֶּאֱמַר: “וְתִיטַב לַה׳ מִשּׁוֹר פָּר מַקְרִין מַפְרִיס״. ‘מַקְרִין׳ תַּרְתֵּי מַשְׁמַע! אָמַר רַב נַחְמָן בַּר יִצְחָק: ‘מִקֶּרֶן׳ כְּתִיב. וְלִיפְשׁוֹט מִינֵּיהּ דְּמִין בְּהֵמָה הוּא! כֵּיוָן דְּאִיכָּא קֶרֶשׁ דְּמִין חַיָּה הוּא, וְלֵית לֵיהּ אֶלָּא חֲדָא קֶרֶן – אִיכָּא לְמֵימַר מִין חַיָּה הוּא.

The Gemara comments: From the fact that it is said that the taḥash had a single horn on its forehead, conclude from this that it was kosher, as Rav Yehuda said in a similar vein: The ox that Adam, the first man, sacrificed as a thanks-offering for his life being spared, had a single horn on its forehead, as it is stated: “And it shall please the Lord better than a horned [ makrin ] and hooved ox” (Psalms 69:32). The word makrin means one with a horn. The Gemara asks: On the contrary, makrin indicates that it has two horns. Rav Naḥman bar Yitzḥak said: Despite the fact that it is vocalized in the plural, it is written mikeren without the letter yod to indicate that it had only a single horn. The Gemara asks: If so, let us resolve from the same baraita that just as it was derived from the ox of Adam, the first man, that an animal with one horn is kosher, derive that an animal with one horn is a type of domesticated animal. The Gemara answers: Since there is the keresh which is a type of undomesticated animal, and it has only a single horn, it is also possible to say that the taḥash is a type of undomesticated animal. This dilemma was not resolved.

מתני׳ פְּתִילַת הַבֶּגֶד שֶׁקִּיפְּלָהּ וְלֹא הִבְהֲבָהּ, רַבִּי אֱלִיעֶזֶר אוֹמֵר: טְמֵאָה הִיא וְאֵין מַדְלִיקִין בָּהּ, רַבִּי עֲקִיבָא אוֹמֵר: טְהוֹרָה הִיא וּמַדְלִיקִין בָּהּ.

The wick of a garment, i.e., cloth made into a wick for a lamp, that one folded it into a size and shape suitable for a wick, but did not yet singe it slightly in order to facilitate its lighting, Rabbi Eliezer says: This wick is ritually impure. With regard to the laws of ritual impurity, it can, like other garments, still become ritually impure and one may not light with it on Shabbat. Rabbi Akiva says: It is ritually pure and one may even light with it on Shabbat.

גמ׳ בִּשְׁלָמָא לְעִנְיַן טוּמְאָה – בְּהָא פְּלִיגִי, דְּרַבִּי אֱלִיעֶזֶר סָבַר: קִיפּוּל אֵינוֹ מוֹעִיל, וּבְמִילְּתֵיהּ קַמַיָּיתָא קָיְימָא. וְרַבִּי עֲקִיבָא סָבַר: קִיפּוּל מוֹעִיל וּבַטּוּלֵּי בָּטֵיל.

The Gemara asks: Granted, with regard to ritual impurity, the reasons for their disagreement are clear and this is their dispute: Rabbi Eliezer holds that folding alone is ineffective in altering the identity of the garment and it retains its original status. It can become ritually impure like any other garment. Rabbi Akiva holds that folding is effective, and it negates its garment status, and therefore, it can no longer become ritually impure.

אֶלָּא לְעִנְיַן הַדְלָקָה בְּמַאי פְּלִיגִי? אָמַר רַבִּי אֶלְעָזָר אָמַר רַב אוֹשַׁעְיָא, וְכֵן אָמַר רַב אַדָּא בַּר אַהֲבָה: הָכָא בְּשָׁלֹשׁ עַל שָׁלֹשׁ מְצוּמְצָמוֹת עָסְקִינַן, וּבְיוֹם טוֹב שֶׁחָל לִהְיוֹת עֶרֶב שַׁבָּת עָסְקִינַן, דְּכּוּלֵּי עָלְמָא אִית לְהוּ דְּרַבִּי יְהוּדָה, דְּאָמַר: מַסִּיקִין בְּכֵלִים וְאֵין מַסִּיקִין בְּשִׁבְרֵי כֵלִים, וּדְּכוּלֵּי עָלְמָא אִית לְהוּ דְּעוּלָּא, דְּאָמַר עוּלָּא: הַמַּדְלִיק צָרִיךְ שֶׁיַּדְלִיק בְּרוֹב הַיּוֹצֵא. רַבִּי אֱלִיעֶזֶר סָבַר: קִיפּוּל אֵינוֹ מוֹעִיל, וְכֵיוָן דְּאַדְלִיק בֵּיהּ פּוּרְתָּא – הָוְיָא לֵיהּ שֶׁבֶר כְּלִי, וְכִי קָא מַדְלִיק – בְּשֶׁבֶר כְּלִי קָמַדְלִיק. וְרַבִּי עֲקִיבָא סָבַר: קִיפּוּל מוֹעִיל, וְאֵין תּוֹרַת כְּלִי עָלָיו, וְכִי קָמַדְלִיק – בְּעֵץ בְּעָלְמָא קָמַדְלִיק.

However, with regard to lighting on Shabbat what is at the crux of their dispute? Rabbi Elazar said that Rav Oshaya said, and Rav Adda bar Ahava said likewise: Here we are dealing with a cloth that is precisely three by three fingerbreadths and we are dealing with a Festival that occurred on Shabbat eve. And everyone is of the opinion that the halakha is in accordance with the opinion of Rabbi Yehuda, who said that on a Festival one may only kindle a fire with whole vessels, as it is permitted to carry them and they do not have set-aside [ muktze ] status; however, one may not kindle a fire using broken vessels, i.e., vessels that broke on the Festival. Since they broke on the Festival itself, they are classified as an entity that came into being [ nolad ] halakha prohibits moving them. And, similarly, everyone is of the opinion that the halakha is in accordance with the opinion of Ulla, as Ulla said: One who lights a lamp must light most of the wick that protrudes from the lamp. Based on these assumptions, the dispute in the mishna can be understood as follows: Rabbi Eliezer holds that folding alone is ineffective in negating the wick’s vessel status, and once one lights only a small part of it, it thereby becomes a broken vessel, as part of it burns and the remainder is less than three by three fingerbreadths. A smaller cloth is no longer considered significant. Since he is required to light most of the protruding wick and, as mentioned above, it is prohibited to light broken vessels, he may not light the folded garment. And Rabbi Akiva held that folding is effective and, immediately when he folded it, the garment no longer has the status of a vessel. It was not considered a vessel even before he lit it, and when he lights it, it is as if he were lighting plain wood, not a vessel that broke on the Festival.

אָמַר רַב יוֹסֵף, הַיְינוּ דְּתָנֵינָא: “שָׁלֹשׁ עַל שָׁלֹשׁ מְצוּמְצָמוֹת״ וְלָא יָדַעֲנָא לְמַאי הִלְכְתָא.

Rav Yosef said, that is what I learned: Three by three exactly. And I did not know to what halakha this was relevant. Rav Yosef received from his teachers that the baraita is referring to a case of three by three exactly, and he did not know why it was significant to establish the baraita in a case of exactly three by three and no more.

וּמִדְּקָא מְתָרֵץ רַב אַדָּא בַּר אַהֲבָה אַלִּיבָּא דְּרַבִּי יְהוּדָה – שְׁמַע מִינָּהּ כְּרַבִּי יְהוּדָה סְבִירָא לֵיהּ; וּמִי אָמַר רַב אַדָּא בַּר אַהֲבָה הָכִי? וְהָאָמַר רַב אַדָּא בַּר אַהֲבָה:

The Gemara adds incidentally: And from the fact that Rav Adda bar Ahava interpreted this mishna in accordance with the opinion of Rabbi Yehuda, conclude from this that he holds in accordance with the opinion of Rabbi Yehuda. Did Rav Adda bar Ahava actually say this? Didn’t Rav Adda bar Ahava himself say:
