Leviticus 11:44; Leviticus 11:46; Leviticus 20:25

44 '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.

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,

25 'You are therefore to make a distinction between the clean animal and the unclean, and between the unclean bird and the clean; and you shall not make yourselves detestable by animal or by bird or by anything that creeps on the ground, which I have separated for you as unclean.
