Leviticus 20:24-26

20:24 So I have said to you: You yourselves will possess their land and I myself will give it to you for a possession, a land flowing with milk and honey. I am the Lord your God who has set you apart from the other peoples. 20:25 Therefore you must distinguish between the clean animal and the unclean, and between the unclean bird and the clean, and you must not make yourselves detestable by means of an animal or bird or anything that creeps on the ground – creatures I have distinguished for you as unclean. 20:26 You must be holy to me because I, the Lord, am holy, and I have set you apart from the other peoples to be mine.
