Leviticus 11:44, 45
For I am the LORD your God; consecrate yourselves, therefore, and be holy, because I am holy. You must not defile yourselves by any creature that crawls along the ground. / For I am the LORD, who brought you up out of the land of Egypt so that I would be your God; therefore be holy, because I am holy.
