Deuteronomy 14:7-8

7However, of those that chew the cud or that have a divided hoof you may not eat the camel, the rabbit or the hyrax. Although they chew the cud, they do not have a divided hoof; they are ceremonially unclean for you.

8The pig is also unclean; although it has a divided hoof, it does not chew the cud. You are not to eat their meat or touch their carcasses.
