Leviticus 11:1, 4, 41-44

And the LORD spoke to Moses and Aaron, saying to them

Nevertheless, among those that chew the cud or part the hoof, you shall not eat these: The camel, because it chews the cud but does not part the hoof, is unclean to you.

“Every swarming thing that swarms on the ground is detestable; it shall not be eaten. Whatever goes on its belly, and whatever goes on all fours, or whatever has many feet, any swarming thing that swarms on the ground, you shall not eat, for they are detestable. You shall not make yourselves detestable with any swarming thing that swarms, and you shall not defile yourselves with them, and become unclean through them. For I am the LORD your God. Consecrate yourselves therefore, and be holy, for I am holy. You shall not defile yourselves with any swarming thing that crawls on the ground.
