Leviticus 11:43-45

You shall not make yourselves detestable with any swarming thing that swarms, and you shall not defile yourselves with them, and become unclean through them. For I am the Lord your God. Consecrate yourselves therefore, and be holy, for I am holy. You shall not defile yourselves with any swarming thing that crawls on the ground. For I am the Lord who brought you up out of the land of Egypt to be your God. You shall therefore be holy, for I am holy.”
