Leviticus 11:39-45

39“‘Now if an animal that you may eat dies, whoever touches its carcass will be unclean until the evening.

40One who eats from its carcass must wash his clothes and be unclean until the evening, and whoever carries its carcass must wash his clothes and be unclean until the evening.

41Every swarming thing that swarms on the land is detestable; it must not be eaten.

42You must not eat anything that crawls on its belly or anything that walks on all fours or on any number of legs of all the swarming things that swarm on the land, because they are detestable.

43Do not make yourselves detestable by any of the swarming things. You must not defile yourselves by them and become unclean by them,

44for I am the Lord your God and you are to sanctify yourselves and be holy because I am holy. You must not defile yourselves by any of the swarming things that creep on the ground,

45for I am the Lord who brought you up from the land of Egypt to be your God, and you are to be holy because I am holy.
