The insides of a melon and that which is cut from a vegetable that are terumah, R' Dosa permits [their consumption] by non-Kohanim, but the Sages prohibit [their consumption by non-Kohanim]. Five sheep, each of which is shorn of [wool that weighs] a maneh and a half, are subject to the [law of the] first fleece, these are the words of R' Dosa. But the Sages say: Five sheep [shorn of wool that weighs] any amount [are subject to the obli-gation].
