Leviticus 11:42-47
42 You are not to eat any creature that moves about on the ground, whether it moves on its belly or walks on all fours or on many feet; it is detestable.
43 Do not defile yourselves by any of these creatures. Do not make yourselves unclean by means of them or be made unclean by them.
44 I am the Lord your God; consecrate yourselves and be holy, because I am holy. Do not make yourselves unclean by any creature that moves about on the ground.
45 I am the Lord who brought you up out of Egypt to be your God; therefore be holy, because I am holy.
46 “‘These are the regulations concerning animals, birds, every living thing that moves in the water and every creature that moves about on the ground.
47 You must distinguish between the unclean and the clean, between living creatures that may be eaten and those that may not be eaten.’”
