Deuteronomy 14:7-8

7But you must not eat these animals: camels, wild rabbits and rock badgers. They eat their food a second time, but they do not have feet with two separate parts. For this reason they are unclean food for you.

8You may not eat pigs, either. They have feet in two parts but they do not eat their food a second time. You must not eat any meat from these animals. You must not even touch their dead bodies.
