Leviticus 20:19-21

Holman Christian Standard Bible

¹⁹ You must not have sexual intercourse with your mother’s sister or your father’s sister,^(A) 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;^(B) they will bear their guilt and die childless. ²¹ If a man marries his brother’s wife, it is impurity.^(C) He has shamed his brother;^(D) they will be childless.
