Leviticus 18:15-17

Common English Bible

¹⁵ You must not have sexual contact with your daughter-in-law; she is your son’s wife. You must not have sexual contact with her. ¹⁶ You will not uncover the nakedness of your brother’s wife; it is your brother’s nakedness.

¹⁷ You must not have sexual contact with a woman and her daughter. You will not marry her son’s daughter or her daughter’s daughter, thereby uncovering her nakedness. They are her blood relatives; it is shameful.
