'Chew' in the Bible

Nevertheless, you are not to eat these, among those which chew the cud or divide the hoof: the camel, because it chews the cud but does not divide the hoof; it is [ceremonially] unclean to you.

And the swine, because it divides the hoof and makes a split hoof, but does not chew the cud; it is unclean to you.

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