Leviticus 20:20-24
English Standard Version
Chapter 20
20If a man lies with his uncle 's wife, he has uncovered his uncle 's nakedness; they shall bear their sin; they shall die childless. 21If a man takes his brother 's wife, it is impurity. He has uncovered his brother 's nakedness; they shall be childless.
22"You shall therefore keep all my statutes and all my rules and do them, that the land where I am bringing you to live may not vomit you out.
23And you shall not walk in the customs of the nation that I am driving out before you, for they did all these things, and therefore I detested them.
24But I have said to you, ‘You shall inherit their land, and I will give it to you to possess, a land flowing with milk and honey.’ I am the Lord your God, who has separated you from the peoples.
