Leviticus 20:17-19

Holman Christian Standard Bible

¹⁷ If a man marries his sister,^(A) whether his father’s daughter or his mother’s daughter, and they have sexual relations,^[a](B) it is a disgrace.^(C) They must be cut off publicly from their people. He has had sexual intercourse with his sister; he will bear his punishment. 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.^(D) 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,^(E) for it is exposing one’s own blood relative; both people will bear their punishment.
