Leviticus 11:44-47

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. [1 Thess 4:7, 8] For I am the LORD who brought you up from the land of Egypt to be your God; therefore you shall be holy, for I am holy.’ ” [1 Pet 1:14-16] 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, 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.
