Leviticus 20:18-20

Complete Jewish Bible

¹⁸ If a man goes to bed with a woman in her menstrual period and has sexual relations with her, he has exposed the source of her blood, and she has exposed the source of her blood; both of them are to be cut off from their people. ¹⁹ You are not to have sexual relations with your mother’s sister or your father’s sister; a person who does this has had sexual relations with his close relative; they will bear the consequences of their wrongdoing. ²⁰ If a man goes to bed with his uncle’s wife, he has disgraced his uncle sexually; they will bear the consequences of their sin and die childless.
