Deuteronomy 14
7 Ref Nevertheless these you shall not eat of them that chew the cud, or of those who have the hoof cloven: the camel, and the hare, and the rabbit; because they chew the cud but don't part the hoof, they are unclean to you.
8 Ref The pig, because it has a split hoof but doesn't chew the cud, is unclean to you: of their flesh you shall not eat, and their carcasses you shall not touch.
