Deuteronomy 14:7-8

7Only these ye shall not eat of those that chew the cud, or of those with hoofs cloven and split open: the camel, and the hare, and the rock-badger; for they chew the cud, but have not cloven hoofs — they shall be unclean unto you;

8and the swine, for it hath cloven hoofs, yet cheweth not the cud — it shall be unclean unto you. Of their flesh shall ye not eat, and their carcase shall ye not touch.
