Leviticus 20:24-26

24But I have promised you, ‘You will possess their land because I will give it to you as your possession—a land flowing with milk and honey.’ I am the Lord your God, who has set you apart from all other people.

25“You must therefore make a distinction between ceremonially clean and unclean animals, and between clean and unclean birds. You must not defile yourselves by eating any unclean animal or bird or creature that scurries along the ground. I have identified them as being unclean for you.

26You must be holy because I, the Lord, am holy. I have set you apart from all other people to be my very own.
