Jerusalem Talmud Peah 3.4

משנה: הָאַחִים שֶׁחָלְקוּ נוֹתְנִין שְׁתֵּי פֵיאוֹת. חָזְרוּ וְנִשְׁתַּתְּפוּ נוֹתְנִין פֵּיאָה אַחַת. שְׁנַיִם שֶׁלָּקְחוּ אֶת הֵאִילָן נוֹתְנִין פֵּיאָה אַחַת. לָקַח זֶה צְפוֹנוֹ וְזֶה דְרוֹמוֹ זֶה נוֹתֵן פֵּיאָה לְעַצְמוֹ וְזֶה נוֹתֵן פֵּיאָה לְעַצְמוֹ.

MISHNAH: Brothers who split give two peot. When they later form a cooperative, they give one peah. Two people who together bought a tree give one peah. If one bought the North side and the other the South side, each gives peah for himself.

הלכה: קָצַר חֲצִי שָׂדֶה בְשוּתְפוּת וְחָלְקוּ אֵינוֹ מַפְרִישׁ מִשֶּׁלּוֹ לֹא בִתְחִילָּה וְלֹא בְסוֹף. חָזְרוּ וְחָלְקוּ וְנִשְתַּתְּפוּ וְקָצְרוּ חֲצִי שָׂדֶה בְשׁוּתְפוּת וְחָלְקוּ מַפְרִישׁ שֶׁבְּסוֹף עַל חֲבֵירוֹ שֶׁבְּסוֹף. אֲבָל לֹא מִשֶׁלּוֹ שֶׁבִּתְחִילָּה עַל חֲבֵירוֹ שֶׁבִּתְחִילָּה.

HALAKHAH: If he harvested half a field in company [with his brother] and then they split up, he does not give from his own part either for the initial harvest or for the final one. When they changed their minds and after splitting formed a company and harvested half a field, and then separated again, he can give from his part at the end for his partner’s part at the end, but not from his part at the start for his partner’s part at the start.

אָמַר רִבִּי יוֹחָנָן קָצַר חֲצִי שָׂדֶה וְקָצַר חֲצִי חֶצְיָיהּ וְלֹא הִסְפִּיק לִקְצוֹר אֶת הַשְּׁאָר עַד שֶׁקָּצַר כּוּלָּהּ מַפְרִישׁ מִן הָרִאשׁוֹן עַל הָאֶמצָעִיִין וּמִן הָאֶמצָעִיִין עַל הָרִאשׁוֹן. וְאֵינוֹ מַפְרִישׁ מִן הָרִאשׁוֹן עַל הָרִאשׁוֹן. אָמַר רִבִּי יְהוֹשֻׁעַ בֶּן לֵוִי הָיְתָה לוֹ שָׂדֶה אַחַת חֶצְיָיהּ הֵבִיאָה שְׁלִישׁ וְחֶצְיָיהּ לֹא הֵבִיאָה שְׁלִישׁ וְלא הִסְפִּיק לִקְצוֹר חֲצִי חֶצְיָיהּ עַד שֶׁהֵבִיאָה כוּלָּהּ שְׁלִישׁ מַפְרִיש מִן הָרִאשׁוֹן עַל הָאֶמצָעִיִים וּמִן הָאֶמצָעִיִים עַל הָרִאשׁוֹן וְאֵינוֹ מַפְרִישׁ מִן הָרִאשׁוֹן עַל הָרִאשׁוֹן.

Rebbi Joḥanan said: If he wanted to cut half of his field and actually cut half of this half, but when he came to cut the other half he finished off his entire field, then he may give from the first cut on the intermediate ones and from the intermediate ones on the first but not from the first on the first. Rebbi Joshua ben Levi said: If he had a field where half of it was one third ripe, the other half was not yet one third ripe, and by the time he finished harvesting half of the first half, the entire field also was one third ripe, he gives from the first cut on the intermediate ones and from the intermediate ones on the first but not from the first on the first.
