Leviticus 11:43

39 If an animal that you may eat dies, anyone who touches the carcass will be unclean until evening.

40 Whoever eats from the carcass must wash his clothes and will be unclean until evening, and anyone who picks up the carcass must wash his clothes and will be unclean until evening.

41 Every creature that moves along the ground is detestable; it must not be eaten.

42 Do not eat any creature that moves along the ground, whether it crawls on its belly or walks on four or more feet; for such creatures are detestable.

43 Do not defile yourselves by any crawling creature; do not become unclean or defiled by them.

44 For I am the LORD your God; consecrate yourselves, therefore, and be holy, because I am holy. You must not defile yourselves by any creature that crawls along the ground.

45 For I am the LORD, who brought you up out of the land of Egypt so that I would be your God; therefore be holy, because I am holy.

46 This is the law regarding animals, birds, all living creatures that move in the water, and all creatures that crawl along the ground.

47 You must distinguish between the unclean and the clean, between animals that may be eaten and those that may not.’”
