'Chew the Cud' in the Bible

Nevertheless these shall ye not eat of those that chew the cud, or of those that part the hoof: the camel, because he chews the cud but does not part the hoof, he is unclean to you.

And the swine, because he parts the hoof, and is cloven footed, but does not chew the cud, he is unclean to you.
