Leviticus 11:2-4

2“Speak to the children of Israel, saying, ‘Among all the animals which are on the earth, these are the animals which you may eat.

3You 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.

4Nevertheless, 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.
