'Cloven footed' in the Bible

Whatever divides the hoof, and is cloven-footed, chewing the cud, among the animals, that you shall eat.

And the swine, though he divides the hoof and is cloven-footed, yet he does not chew the cud; he is unclean to you.

even every living thing which divides the hoof, and is not cloven-footed, nor chews the cud, they are unclean to you. Everyone that touches them shall be unclean.
