Leviticus 11:2-8

“Speak to the children of Israel, saying, ‘Among all the animals which are on the earth, these are the animals which you may eat. [Mark 7:15-19] You may eat any animal that has a divided hoof [that is, a hoof split into two parts especially at its distal extremity] and chews the cud. Nevertheless, you are not to eat these, among those which chew the cud or divide the hoof: the camel, because it chews the cud but does not divide the hoof; it is [ceremonially] unclean to you. And the shaphan, because it chews the cud but does not divide the hoof; it is unclean to you. And the hare, because it chews the cud but does not divide the hoof; it is unclean to you. And the swine, because it divides the hoof and makes a split hoof, but does not chew the cud; it is unclean to you. You shall not eat their meat nor touch their carcasses; they are unclean to you.
