Leviticus 20:24-26

24I, the Lord, will give their land to Israel's people. I will give it to you and to your children to keep for all time. In that land, there is plenty of food and drink, enough for everyone. I am the Lord your God. I want you to be separate from other people.

25The people must know which animals are clean. And they must know which animals are unclean. They must know which birds are clean. And they must know which birds are unclean. They must not eat any animal or bird that is unclean.

26I am the Lord and I am holy. So my people must be holy for me. I have made them separate from other people. They belong to me.
