Leviticus 11:41-47 - Unclean Swarming Creatures
41 ‘Now everything that swarms on the ground is detestable; it is not to be eaten. 42 Whatever crawls on its belly, and whatever walks on all fours, and whatever has many feet among all things that swarm on the ground, you shall not eat; for they are detestable. 43 Do not make yourselves loathsome (impure, repulsive) by [eating] any swarming thing; you shall not make yourselves unclean by them so as to defile yourselves. 44 For I am the Lord your God; so consecrate yourselves and be holy, for I am holy. You shall not make yourselves unclean with any of the swarming things that swarm or crawls on the ground.
46 This is the law regarding the animal and the bird and every living thing that moves in the waters and everything that swarms on the earth, 47 to make a distinction between the [ceremonially] unclean and the [ceremonially] clean, and between the animal that may be eaten and the animal that may not be eaten.
