Leviticus 11:4-7

11:4 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. 11:5 The rock badger is unclean to you because it chews the cud even though its hoof is not divided. 11:6 The hare is unclean to you because it chews the cud even though its hoof is not divided. 11:7 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.
