Others say: The verse speaks of offerings which have become invalidated, it being written here "abomination," and, elsewhere, (Ibid. 17:1) "You shall not sacrifice to the L-rd your G-d an ox or a lamb in which there is a blemish, any evil thing, for it is the abomination of the L-rd your G-d." Just as "abomination" there speaks of offerings which have become invalidated (by a blemish), so, "abomination" here.
(Devarim 14:4) "This is the beast that you may eat: the ox, the lamb of sheep, and the kid of goats, the hart, the gazelle, and the fallow deer" — whence we derive that animals (the last three) are in the category of "beast." Whence do we derive that a beast is in the category of "animal"? From (Vayikra 11:2) "This is the animal that you shall eat from all of the beasts" — whence it is derived that an animal is called a beast, and a beast, an animal.
