Leviticus 18:7-9

Common English Bible

⁷ You must not uncover your father’s nakedness, which is your mother’s nakedness. She is your mother; you must not have sexual contact with her. ⁸ You must not uncover the nakedness of your father’s wife; it is your father’s nakedness. ⁹ You must not have sexual contact with your sister—regardless of whether she is your father’s daughter or your mother’s daughter, whether born into the same household as you or outside it.
