'Split' in the Bible

Whatever divides a hoof, thus making split hoofs, and chews the cud, among the animals, that you may eat.

and the pig, for though it divides the hoof, thus making a split hoof, it does not chew cud, it is unclean to you.

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