Deuteronomy 14:3-8

Thou shalt not eat any abominable thing. These are the beasts which ye may eat: the ox, the sheep, and the goat, the hart, and the gazelle, and the roebuck, and the wild goat, and the pygarg, and the antelope, and the chamois. And every beast that parteth the hoof, and hath the hoof cloven in two, and cheweth the cud, among the beasts, that may ye eat. Nevertheless these ye shall not eat of them that chew the cud, or of them that have the hoof cloven: the camel, and the hare, and the coney; because they chew the cud but part not the hoof, they are unclean unto you. And the swine, because he parteth the hoof but cheweth not the cud, he is unclean unto you: of their flesh ye shall not eat, and their carcasses ye shall not touch.
