'Chew' in the Bible

Nevertheless these ye shall not eat of them that chew the cud, or of them that divide the cloven hoof; as the camel, and the hare, and the coney: for they chew the cud, but divide not the hoof; therefore they are unclean unto you.

and the pig, though it has hooves, it does not chew the cud—it is unclean for you.You must not eat their meat or touch their carcasses.
