Jerusalem Talmud Peah 1.2

משנה: אֵין פּוֹחְתִין לְפֵיאָה מִשִּׁשִּׁים. אַף עַל פִּי שֶׁאָמְרוּ אֵין לְפֵיאָה שֵׁיעוּר הַכֹּל לְפִי גוֹדֶל הַשָּׂדֶה וּלְפִי הָעֲנִיים וּלְפִי הֲעֲנָוָה.

MISHNAH: One never gives peah less than one in sixty. Even though they said that peah has no measure, everything is according to the size of the field, the poor, and the humility.

הלכה: תַּנִּי אֵין אוֹמְרִים לוֹ הֲבֵא גְמָלִים וּטְעוֹן. מִתְנִיתָא בְּיֶתֶר מִכְּשֵׁיעוּר. אֲבָל בִּכְּשֵׁיעוּר אוֹמְרִים לוֹ הֲבֵא גְמָלִים וּטְעוֹן. שָׂדֵהוּ מְרוּבָּה וַעֲנִיִים מוּעָטִין נוֹתֵן לְפִי שָׂדֵהוּ. שָׂדֵהוּ מְעוּטָה וַעֲנִיִים מְרוּבִּין נוֹתֵן לְפִי הָעֲנִיִים. רִבִּי שִׁמְעוֹן דָּרַשׁ שְׁנֵי דְּבָרִים לְקֻלּוֹ שֶׁל בַּעַל הַבַּיִת. שָׂדֵהוּ מְרוּבָּה וַעֲנִיִים מְמוּעָטִין נוֹתֵן לְפִי הָעֲנִיִים. שָׂדֵהוּ מְעוּטָה וַעֲנִיִים מְרוּבִּין נוֹתֵן לְפִי שָׂדֵהוּ. מַתְנִיתָא לֹא אָמַר כֵּן אֶלָּא הַכֹּל לְפִי גוֹדֶל הַשָּׂדֶה וּלְפִי הָעֲנִיים וּלְפִי הֲעֲנָוָה.

HALAKHAH: It was stated: One does not say to him, bring camels and load up. The baraita speaks if he wants to give more than the measure, but if he gives according to the measure then one says to the poor to bring camels and load up. If his field is large and the poor few, he gives according to the field. His field is small and the poor many, he gives according to the poor. Rebbi Simeon explained two things to make it easy for the owner: If his field is large and the poor few, he gives according to the poor; if his field is small and the poor many, he gives according to the field. The Mishnah does not say so, but “everything is according to the size of the field, the poor, and the humility (yield).”
