Leviticus 11:41-44

41‘1Now every swarming thing that swarms on the earth is detestable, not to be eaten.

42Whatever crawls on its belly, and whatever walks on all fours, whatever has many feet, in regard to every swarming thing that swarms on the earth, you shall not eat them, because they are detestable.

432Do not make 3yourselves detestable through any of the swarming things that swarm; and you shall not make yourselves unclean with them so that you become unclean.

44For 4I am the Lord your God. Consecrate yourselves therefore, and 5be holy, because I am holy. And you shall not make yourselves unclean with any of the swarming things that swarm on the earth.
