Deuteronomy 14:7-8

New Revised Standard Version Catholic Edition

⁷ Yet of those that chew the cud or have the hoof cleft you shall not eat these: the camel, the hare, and the rock badger, because they chew the cud but do not divide the hoof; they are unclean for you. ⁸ And the pig, because it divides the hoof but does not chew the cud, is unclean for you. You shall not eat their meat, and you shall not touch their carcasses.
