Leviticus 18:16-18

Common English Bible

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. ¹⁸ You must not marry your wife’s sister as a rival and have sexual contact with her while her sister is alive.
