'Chew' in the Bible

Nevertheless, you are not to eat of these, among those which chew the cud, or among those which divide the hoof: the camel, for though it chews cud, it does not divide the hoof, it is unclean to you.

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.
