Leviticus 20:21

18 `And a man who lieth with a sick woman, and hath uncovered her nakedness, her fountain he hath made bare, and she hath uncovered the fountain of her blood, --even both of them have been cut off from the midst of their people.

19 `And the nakedness of thy mother's sister, and of thy father's sister, thou dost not uncover; because his relation he hath made bare; their iniquity they bear.

20 `And a man who lieth with his aunt, the nakedness of his uncle he hath uncovered; their sin they bear; childless they die.

21 `And a man who taketh his brother's wife--it is impurity; the nakedness of his brother he hath uncovered; childless they are.

22 `And ye have kept all My statutes, and all My judgments, and have done them, and the land vomiteth you not out whither I am bringing you in to dwell in it;

23 and ye walk not in the statutes of the nation which I am sending away from before you, for all these they have done, and I am wearied with them;

24 and I say to you, Ye--ye do possess their ground, and I--I give it to you to possess it, a land flowing with milk and honey; I am Jehovah your God, who hath separated you from the peoples.
