'Cloven footed' in the Bible

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.

And the swine, because it divides the hoof and makes a split hoof, but does not chew the cud; it is unclean to you.

Concerning all the animals which divide the hoof, but do not have a split hoof, or which do not chew the cud, they are unclean to you; whoever touches them becomes unclean.
