Leviticus 20:24-26

24But I have said to you, ‘You will inherit their land and I will give it to you to possess it, a land flowing with milk and honey.’ I am Adonai your God, who has set you apart from the peoples.

25“Also you are to make a distinction between the clean animal and the unclean, and between the unclean bird and the clean. And you are not to make your souls detestable by an animal or by a bird, or by anything with which the ground teems, which I have set apart as unclean for you.

26You are to be holy to Me, for I, Adonai, am holy, and have set you apart from the peoples, so that you would be Mine.
