Leviticus 11:3-7

Whatever has a divided hoof, showing 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 have a divided hoof: the camel, for though it chews cud, it does not have a divided hoof; it is unclean to you.

Likewise, the rock hyrax, for though it chews cud, it does not have a divided hoof; it is unclean to you.

The rabbit also, for though it chews cud, it does not have a divided hoof; it is unclean to you.

And the pig, for though it has a divided hoof, and so it shows a split hoof, it does not chew cud; it is unclean to you.
