'Chew the Cud' in the Bible

However, you must not eat these from among those that chew the cud and have divided hooves: The camel is unclean to you because it chews the cud even though its hoof is not divided.

The pig is unclean to you because its hoof is divided (the hoof is completely split in two), even though it does not chew the cud.

"'All animals that divide the hoof but it is not completely split in two and do not chew the cud are unclean to you; anyone who touches them becomes unclean.
