Talmud for Eduyot 3:3
מְעֵי אֲבַטִּיחַ וּקְנִיבַת יָרָק שֶׁל תְּרוּמָה, רַבִּי דוֹסָא מַתִּיר לְזָרִים, וַחֲכָמִים אוֹסְרִין. חָמֵשׁ רְחֵלוֹת גְּזוּזוֹת מָנֶה מָנֶה וּפְרַס, חַיָּבוֹת בְּרֵאשִׁית הַגֵּז, דִּבְרֵי רַבִּי דוֹסָא. וַחֲכָמִים אוֹמְרִים, חָמֵשׁ רְחֵלוֹת כָּל שֶׁהֵן:
R. Dossa permits the innards [i.e., the seeds and the juice] of a melon and the discards of greens (of terumah) to zarim (non-Cohanim), and the sages forbid them. The shearings of five lambs, [each lamb] yielding a maneh and a half of wool, [less than that not being considered "shearings," this being the minimum] are subject to the mitzvah of "the first of the shearings" — These are the words of R. Dossa. The sages say: five lambs, any amount (of shearings). [Not really, for the rabbis did not mandate "the first of the shearings" for less than sixty selaim. But since R. Dossa required a (relatively) large amount, the tanna called the small amount of the sages "any amount." (The weight of a sela is twenty-four ma'im, and the weight of each ma'ah, sixteen barley grains.)]
