Leviticus 20:19-21

New American Standard Bible

^19 (A)You shall also not uncover the nakedness of your mother’s sister or of your father’s sister, for such a one has uncovered his ^[a]blood relative; they will bear their guilt. ^20 (B)If there is a man who sleeps with his uncle’s wife, he has uncovered his uncle’s nakedness; they will bear their sin. They will die childless. ^21 (C)If there is a man who takes his brother’s wife, it is ^[b]detestable; he has uncovered his brother’s nakedness. They will be childless.
