Leviticus 11:44-47

For I am the LORD your God. Consecrate yourselves therefore, and be holy, for I am holy. And you shall not make yourselves unclean with any of the swarming things that swarm on the earth. For I am the LORD who brought you up from the land of Egypt to be your God; thus you shall be holy, for I am holy.’ ” 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 unclean and the clean, and between the edible creature and the creature which is not to be eaten.
