Lev 20:24-26

24But I have said to you: You shall inherit their land, and I will give it to you to possess, a land flowing with milk and honey. I am the Lord your God; I have separated you from the peoples.25You shall therefore make a distinction between the clean animal and the unclean, and between the unclean bird and the clean; you shall not bring abomination on yourselves by animal or by bird or by anything with which the ground teems, which I have set apart for you to hold unclean.26You shall be holy to me; for I the Lord am holy, and I have separated you from the other peoples to be mine.
