Leviticus 11:2-8

“Speak to the sons of Israel, saying, ‘These are the creatures which you may eat from all the animals that are on the earth. Whatever divides a hoof, thus making split hoofs, and chews the cud, among the animals, that you may eat. Nevertheless, you are not to eat of these, among those which chew the cud, or among those which divide the hoof: the camel, for though it chews cud, it does not divide the hoof, it is unclean to you. Likewise, the shaphan, for though it chews cud, it does not divide the hoof, it is unclean to you; the rabbit also, for though it chews cud, it does not divide the hoof, it is unclean to you; and the pig, for though it divides the hoof, thus making a split hoof, it does not chew cud, it is unclean to you. You shall not eat of their flesh nor touch their carcasses; they are unclean to you.
