Leviticus 20:24-26

24But I said to you, “You will possess their land; I will give it to you as an inheritance, a land flowing with milk and honey.” I am the Lord your God, who has set you apart from the nations.

25“ ‘You must therefore make a distinction between clean and unclean animals and between unclean and clean birds. Do not defile yourselves by any animal or bird or anything that moves along the ground—those that I have set apart as unclean for you.

26You are to be holy to me because I, the Lord, am holy, and I have set you apart from the nations to be my own.
