Leviticus 11:2-8

“Speak to the children of Israel, saying, ‘These are the animals which you may eat among all the animals that are on the earth: Among the animals, whatever divides the hoof, having cloven hooves and chewing the cud—that you may eat. Nevertheless these you shall not eat among those that chew the cud or those that have cloven hooves: the camel, because it chews the cud but does not have cloven hooves, is unclean to you; the rock hyrax, because it chews the cud but does not have cloven hooves, is unclean to you; the hare, because it chews the cud but does not have cloven hooves, is unclean to you; and the swine, though it divides the hoof, having cloven hooves, yet does not chew the cud, is unclean to you. Their flesh you shall not eat, and their carcasses you shall not touch. They are unclean to you.
