Jerusalem Talmud Pesachim 3:7

משנה: הַהוֹלֵךְ לִשְׁחוֹט אֶת פִּסְחוֹ וְלָמוּל אֶת בְּנוֹ וְלֶאֱכוֹל סְעוּדַת אֵירוּסִין בְּבֵית חָמִיו וְנִזְכַּר שֶׁיֶּשׁ לוֹ חָמֵץ בְּתוֹךְ בֵּיתוֹ אִם יָכוֹל לַחֲזוֹר וּלְבַעֵר וְלַחֲזוֹר לְמִצְוָתוֹ יַחֲזוֹר. וְאִם לֹא יְבַטֵּל בְלִיבּוֹ. לְהַצִּיל מִיַּד הַגַּיִיס וּמִיַּד הַנָּהָר וּמִן הַדְּלֵיקָה וּמִן הַמַּפּוֹלֶת יְבַטֵּל בְּלִיבּוֹ. וְלִשְׁבּוֹת שְׁבִיתַת הָֽרְשׁוּת יַחֲזוֹר מִיָּד׃ MISHNAH: A person who goes to slaughter his Passover sacrifice, or to circumcise his son, or to eat the betrothal meal at his father-in-law’s house¹³⁰On the 14th of Nisan., and remembers that he has leavened matter in his house, if he can return, eliminate it, and return to his meritorious deed, he shall return and eliminate; otherwise, he has to nullify it in his thought¹³¹While the condition given in Chapter 2, Note 101, is not strictly satisfied, in an emergency situation mental annulment is sufficient as legal abandonment to satisfy the biblical requirement not to have one’s own leavened matter in his possession.. To save from the army¹³²The Roman army on the march in the Roman empire. Since the soldiers will steal anything not hidden, this is an emergency., or from a river¹³³A flood., or from a conflagration, or from a house collapse, he has to nullify it in his thought¹³⁴These are real emergency situations.. To celebrate the holiday according to his wishes¹³⁵He goes to celebrate the holiday at another place of his choosing, not to fulfill a religious precept., he has to return immediately.

הלכה: אָמַר רִבִּי יוֹסֵה בֵּירִבִּי בּוּן. בּוֹא וּרְאֵה מַה גָדוֹל הוּא הַשָּׁלוֹם שֶׁהוּקָּשׁ לִשְׁנֵי דְבָרִים שֶׁחַייָבִין עֲלֵיהֶן כָּרֵת. HALAKHAH: Rebbi Yose ben Rebbi Abun said, come and see how great is peace that it is bundled with two things about whom one is liable to extirpation¹³⁶In the Mishnah, a meal with his future in-laws is put on the same level as the Passover sacrifice and circumcision; two commandments whose omission is punished by Divine extirpation (Gen. 17:14, Num.9:13)..

מִילַת בְּנוֹ וּשְׁחִיטַת פִּסְחוֹ מִי קוֹדֵם. אָמַר רִבִּי פִינְחָס. מִן מַה דִּכְתִיב הִמּ֧וֹל ל֣וֹ כָל־זָכָ֗ר וְאָז֙ יִקְרַ֣ב לַעֲשׂוֹתוֹ. הָדָא אָֽמְרָה שֶׁמִּילַת בְּנוֹ קוֹדֶמֶת לִשְׁחִיטַת פִּיסְחוֹ. His son’s circumcision and the slaughter of his Passover sacrifice. what has precedence? Rebbi Phineas said, since it is written, all his males have to be circumcided, then he will be admitted to nake it, this implies that his sons’ circumcisions has priority over the slaughter of his Passover sacrifice.

אפילו יָכוֹל לַחֲזוֹר וּלְבָעֵר וְלֵילֵךְ וּלְהַצִּיל. אפילו יָכוֹל לֵילֵךְ וְלִשְׁבּוֹת לַחֲזוֹר וּלְבַטֵּל. Even if he could return and eliminate, or go and save¹³⁷Since the second series of cases in the Mishnah is formulated as apodictic rule, not subject to a condition as in the first series, it follows that a person starting to save from soldiers, flood, fire, and collapse, is not permitted to return and eliminate but forced to annul mentally.. Even if he could go and acquire rest status, return and (nullify) [eliminate]¹³⁸. In the last case, if he leaves his place but not to go to Jerusalem, he is required to return immediately even if he could go to the place of his destination, deposit some food there to symbolically move his dwelling to that place, then return to his own house, eliminate the leavened matter, and return to his place of holiday rest.

מַהוּ [שֶׁאֵין] שְׁבִיתַת הָֽרְשׁוּת. אֶצֶל רַבּוֹ אוֹ אֶצֶל מִי שֶׁהוּא גָדוֹל מִמֶּנּוּ בְחָכְמָה. כָּךְ שָׁנָה רִבִּי. הַמַּעֲשֶׂה קוֹדֵם לַתַּלְמוּד. נִמְנוּ בַּעֲלִיַּית בֵּית אָרִוֹס בְּלוֹד. הַתַּלְמוּד קוֹדֵם לַמַּעֲשֶׂה. [What is]¹³⁹This was written by the scribe and then erased by him; it should be read following G.. (no)¹⁴⁰Addition of the corrector; to be deleted with G. to celebrate the holiday according to his wishes? At his teacher’s or at somebody greater than he in wisdom. Here did Rebbi state that action precedes study¹⁴¹Since the action of eliminating leavened matter, even though it could have been replaced by a declaration of nullification, has precedence over a possibility of further study.. They voted in the upper floor of the house of Arius in Lydda that study precedes action¹⁴²According to the Babli, Qiddušin 40b, this was an early Tannaitic decision following R. Aqiba against R. Tarphon. Ḥagigah 1:7..

רִבִּי אַבָּהוּ שָׁלַח לְרִבִּי חֲנִינָה בְרֵיהּ יִזְכֵּי בְטִיבֵּרִיָּה. אֲתוֹן וְאָֽמְרוּן לֵיהּ. גְּמַל הוּא חֶסֶד. שְׁלַח וַאֲמַר לֵיהּ. הֲמִבְּלִי אֵין קְבָרִים בְּקַיְסָרִין שְׁלַחְתִּיךָ לְטִבֵּרִיָּא. שֶׁכְּבָר נִמְנוּ וְגָֽמְרוּ בַּעֲלִייַת בֵּית אָרִוֹס בְּלוֹד שֶׁהַתַּלְמוּד קוֹדֵם לַמַּעֲשֶׂה. רַבָּנִין דְּקַיְסָרִין אָֽמְרִין. הָדָא דְתֵימַר. בְּשֶׁיֶּשׁ שָׁם מִי שֶׁיַּעֲשֶׂה. אֲבָל אִם אֵין שָׁם מִי שֶׁיַּעֲשֶׂה הַמַּעֲשֶׂה קוֹדֵם. דְּלֹמָא. רִבִּי חִייָה רִבִּי יַסַי רִבִּי אִימִּי עֲנוֹן לְמֵיתֵי גַּבֵּי רִבִּי אֶלְעָזָר. אֲמַר לוֹן. אָן הֲוִיתוֹן. אָֽמְרִין לֵיהּ. גְּמַל חֶסֶד. אֲמַר לוֹן. וְלָא הֲוָה תַמָּן חוֹרָנִין. אָֽמְרִין לֵיהּ. מָגוֹר הֲוָה. Rebbi Abbahu sent his son Rebbi Ḥanina to acquire merit in Tiberias. They came and said to him, he does works of charity¹⁴³Burying the dead.. He sent to tell him, are there no graves in Caesarea¹⁴⁴A reference to Ex. 14:11. that I sent you to Tiberias? For they already voted and decided¹⁴⁵Delete with G. in the upper floor of the house of Arius in Lydda that study precedes action¹⁴⁶Therefore he has to spend his time studying in the Academy there.. The rabbis of Caesaria say, that is, if there is somebody there who will do it. But if nobody is there who will do it, the action has precedence¹⁴⁷In particular, religious obligations of a personal nature, which cannot be delegated, have precedence over study.. Example. Rebbi Ḥiyya, Rebbi Yasa, Rebbi Immi, were late in coming to Rebbi Eleazar. He asked them, where have you been? They told him, performing an act of charity. He asked them, where there no others? They answered him, it was a neighbor¹⁴⁸It was an obligation irrespective of the number of attendees at the funeral..
