Deuteronomy 14:7-8

14:7 However, you may not eat the following animals among those that chew the cud or those that have divided hooves: the camel, the hare, and the rock badger. (Although they chew the cud, they do not have divided hooves and are therefore ritually impure to you). 14:8 Also the pig is ritually impure to you; though it has divided hooves, it does not chew the cud. You may not eat their meat or even touch their remains.
