'Chew the Cud' in the Bible

Nevertheless of those that chew the cud, or of those that have the hoof cloven, these ye shall not eat: the camel, and the hare, and the coney, because they chew the cud but do not part the hoof, they are unclean to you,

and the swine, because he parts the hoof but does not chew the cud, he is unclean to you. Of their flesh ye shall not eat, and their carcasses ye shall not touch.
