Deuteronomy 14:3-8

“You shall not eat any abomination. These are the animals you may eat: the ox, the sheep, the goat, the deer, the gazelle, the roebuck, the wild goat, the ibex, the antelope, and the mountain sheep. Every animal that parts the hoof and has the hoof cloven in two and chews the cud, among the animals, you may eat. Yet of those that chew the cud or have the hoof cloven you shall not eat these: the camel, the hare, and the rock badger, because they chew the cud but do not part the hoof, are unclean for you. And the pig, because it parts the hoof but does not chew the cud, is unclean for you. Their flesh you shall not eat, and their carcasses you shall not touch.
