Deuteronomy 14:7-8

14:7 Nevertheless these ye shall not eat of them that chew the cud, or of them that divide the cloven hoof; [as] the camel, and the hare, and the coney: for they chew the cud, but divide not the hoof; [therefore] they [are] unclean unto you. 14:8 And the swine, because it divideth the hoof, yet cheweth not the cud, it [is] unclean unto you: ye shall not eat of their flesh, nor touch their dead carcase.
