¹⁸ If a man sleeps with a menstruating woman and has sexual intercourse with her, he has exposed the source of her flow, and she has uncovered the source of her blood.^(A) Both of them must be cut off from their people. ¹⁹ You must not have sexual intercourse with your mother’s sister or your father’s sister,^(B) for it is exposing one’s own blood relative; both people will bear their punishment. ²⁰ If a man sleeps with his aunt, he has shamed his uncle;^(C) they will bear their guilt and die childless.
