Shimon b. Azzai says: What is the intent of "Veha'avarta"? From (Leviticus 27:32) "Whatever (beast) passes ('ya'avor') under the staff" (for tithing), I would think that an orphan, too, (is tithed). And this would follow, viz.: If a blemished animal, which is not fit for the altar, enters the shed for tithing, then an orphan, which is fit for the altar, how much more so!—(No,) this is refuted by (the instance of) a purchased animal, which, although it is fit for the altar, does not enter the shed for tithing. No, this may be true of a purchased animal, which was not born in his domain, wherefore it does not enter the shed for tithing, as opposed to an orphan, which was born in his domain, wherefore it should enter the shed for tithing.
