¹⁸ If a man sleeps with a woman during her menstrual period and has sexual contact with her, he has exposed the source of her blood flow and she has uncovered the same. Both of them will be cut off from their people. ¹⁹ You must not have sexual contact with your mother’s sister or your father’s sister, because that exposes your own close relative; both of you will be liable to punishment. ²⁰ If a man has sexual intercourse with his aunt, he has uncovered his uncle’s nakedness. The man and the aunt will be liable to punishment; they will die childless.
