Leviticus 11:42-44

11:42 You 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. 11:43 Do not make yourselves detestable by any of the swarming things. You must not defile yourselves by them and become unclean by them, 11:44 for 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,
