'Chew' in the Bible

However, you may not eat the following animals among those that chew the cud or those that have divided hooves: the camel, the hare, and the rock badger. (Although they chew the cud, they do not have divided hooves and are therefore ritually impure to you).

Also the pig is ritually impure to you; though it has divided hooves, it does not chew the cud. You may not eat their meat or even touch their remains.
