Leviticus 11:1-7

The LORD spoke again to Moses and Aaron, saying to them, “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.
