Bechoros2: 7
שְׁתֵּי רְחֵלוֹת שֶׁלֹּא בִכְּרוּ, וְיָלְדוּ שְׁנֵי זְכָרִים — נוֹתֵן שְׁנֵיהֶם לַכֹּהֵן; זָכָר וּנְקֵבָה — הַזָּכָר לְכֹהֵן. שְׁנֵי זְכָרִים וּנְקֵבָה — אֶחָד לוֹ וְאֶחָד לַכֹּהֵן. רַבִּי טַרְפוֹן אוֹמֵר: הַכֹּהֵן בּוֹרֵר לוֹ אֶת הַיָּפֶה. רַבִּי עֲקִיבָא אוֹמֵר: מְשַׁמְּנִים בֵּינֵיהֶם, וְהַשֵּׁנִי יִרְעֶה עַד שֶׁיִּסְתָּאֵב, וְחַיָּב בַּמַּתָּנוֹת. רַבִּי יוֹסֵי פּוֹטֵר. מֵת אֶחָד מֵהֶן — רַבִּי טַרְפוֹן אוֹמֵר: יַחֲלֹקוּ. רַבִּי עֲקִיבָא אוֹמֵר: הַמּוֹצִיא מֵחֲבֵרוֹ עָלָיו הָרְאָיָה. שְׁתֵּי נְקֵבוֹת וְזָכָר, אוֹ שְׁנֵי זְכָרִים וּשְׁתֵּי נְקֵבוֹת — אֵין כָּאן לַכֹּהֵן כְּלוּם.
[If] two ewes which had not previously given birth bore two males —- he gives them both to a Kohen; [if they bore] a male and a female, the male belongs to a Kohen. [If they bore] two males and a female, one belongs to him and one to a Kohen. R’ Tarfon says: The Kohen selects the better one for himself. R’ Akiva says: The fatter one is at issue between them, while the second [lamb] is left to pasture until it develops a blemish, and it is subject to the law of gifts [to the Kohen]. R’ Yose exempts [it]. [If] one of them died —- R’ Tarfon says: They divide. R’ Akiva says: The burden of proof lies on the one who seeks to exact [something] from the other. [If they bore] two females and a male, or two males and two females, there is nothing here for a Kohen.
Bechoros2: 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: כָּל שֶׁחֲלִיפָיו בְּיַד כֹּהֵן פָּטוּר מִן הַמַּתָּנוֹת. רַבִּי מֵאִיר מְחַיֵּב. מֵת אֶחָד מֵהֶן — רַבִּי טַרְפוֹן אוֹמֵר: יַחֲלֹקוּ. רַבִּי עֲקִיבָא אוֹמֵר: הַמּוֹצִיא מֵחֲבֵרוֹ עָלָיו הָרְאָיָה. זָכָר וּנְקֵבָה — אֵין כָּאן לַכֹּהֵן כְּלוּם.
[If] one which had previously given birth and one which had not previously given birth [now] bore two males —- one belongs to him and one goes to a Kohen. R’ Tarfon says: The Kohen selects the better one for himself. R’ Akiva says: The fatter one is at issue between them, while the second [lamb] is left to pasture until it develops a blemish, and it is subject to the law of gifts [to the Kohen]. R’ Yose exempts [it]; for R’ Yose was wont to say: Whatever has its substitute in the Kohen’s hand is exempt from the law of gifts [to the Kohen]. R’ Meir rules [it] subject [to the gifts]. [If] one of them died —- R’ Tarfon says: They divide. R’ Akiva says: The burden of proof lies on the one who seeks to exact [something] from the other. [If they bore] a male and a female, there is nothing here for a Kohen.
