Talmud sur Bekhorot 2:8
אַחַת בִּכְּרָה וְאַחַת שֶׁלֹּא בִכְּרָה וְיָלְדוּ שְׁנֵי זְכָרִים, אֶחָד לוֹ וְאֶחָד לַכֹּהֵן. רַבִּי טַרְפוֹן אוֹמֵר, הַכֹּהֵן בּוֹרֵר לוֹ אֶת הַיָּפֶה. רַבִּי עֲקִיבָא אוֹמֵר, מְשַׁמְּנִין בֵּינֵיהֶן, וְהַשֵּׁנִי יִרְעֶה עַד שֶׁיִּסְתָּאֵב. וְחַיָּב בַּמַּתָּנוֹת. רַבִּי יוֹסֵי פּוֹטֵר, שֶׁהָיָה רַבִּי יוֹסֵי אוֹמֵר, כֹּל שֶׁחֲלִיפָיו בְּיַד כֹּהֵן, פָּטוּר מִן הַמַתָּנוֹת. רַבִּי מֵאִיר מְחַיֵּב. מֵת אֶחָד מֵהֶן, רַבִּי טַרְפוֹן אוֹמֵר, יַחֲלוֹקוּ. רַבִּי עֲקִיבָא אוֹמֵר, הַמּוֹצִיא מֵחֲבֵרוֹ עָלָיו הָרְאָיָה. זָכָר וּנְקֵבָה, אֵין כָּאן לַכֹּהֵן כְּלוּם:
Si une brebis a déjà mis bas et une autre ne l'a pas fait, et qu'elles donnent naissance à deux mâles, l'un va chez [le propriétaire] et l'autre chez le prêtre. Le rabbin Tarfon dit: Le prêtre choisit le meilleur. Rabbi 'Akiva dit: Nous faisons des compromis. Le second va paître jusqu'à ce qu'il développe une tache, et il est obligé en ce qui concerne les dons [sacerdotaux]. Rabbi Yossi l'exempte parce que Rabbi Yossi dit: Lorsque l'échange va au prêtre, [l'autre animal] est exempté des dons [sacerdotaux]. Le rabbin Meir l'oblige. Si l'un d'entre eux meurt, le rabbin Tarfon dit: Ils se partagent [la valeur de celle qui reste]. Rabbi 'Akiva dit: Celui qui vient extraire de son ami a le fardeau de la preuve. [S'ils donnent naissance à] un homme et une femme, le prêtre ne reçoit rien.
Jerusalem Talmud Gittin
R. Meїr holds that the gifts are due since they would be due if it was known which one was the firstling.
In the Babli, 30a, this is Ulla’s opinion.: “Rebbi Yose says, anything whose replacement is in the Cohen’s hand is freed from the gifts, but Rebbi Meїr obligates.” Did Rebbi Yose not speak only if it did exist? But here, he still needs to sow133Since nobody can acquire anything nonexistent (Ketubot 5:5, Note 113), R. Yose’s argument cannot be applied to our case.! Rebbi Abbahu in the name of Rebbi Joḥanan: The Mishnah speaks of acquaintances of Cohanim or Levites134The expression is Biblical (2K. 12:6,8); it refers to people who regularly give all their priestly gifts or tithes to the same Cohen or Levite. Then heave and tithes have the status of annuities and cannot be said to be nonexistent.
In the Babli, 30a, this is Rav’s opinion. Samuel requires that heave or tithes be actually given to a third party Cohen or Levite, acting as recipient for the debtor, who then returns the produce to the farmer. That opinion has no parallel in the Yerushalmi.. But did we not state “a poor person”? Does a poor person have acquaintances135The tithe of the poor has to be given to the first poor person who applies.? There came a case before Rebbi Immi: A Cohen or Levite who owed money to an Israel and told him136After the loan was given, the debtor then asked to be excused from repayment using the method outlined in the Mishnah., separate from my part for my account. He said to him, did we not state: “If somebody lent money to a Cohen, a Levite, or a poor person to separate on their account.” When the loan was given under these conditions. Therefore, not if it was not a condition of the loan! Rebbi Ze‘ira said, even if it was not a condition of the loan. Rebbi Ze‘ira’s force is from the following137Tosephta Demay 7:15. The Levite cannot tell the Israel to arrange with other farmers that they pay him to give tithes for them and deduct the sum from the Levite’s debt, since no Levite can dispose of another Levite’s tithes.: “Similarly, a Levite who owed money to an Israel and said to him, separate on my account; only he should not collect and separate because no Levite makes a Levite.” He only said, he should not separate138Missing in the text: Other people’s tithes., but from his own he may separate.
