Leviticus 18:7–18

⁷ You must not expose the nakedness of your father by having sexual relations with your mother. She is your mother; you must not have sexual relations with her. ⁸ You must not have sexual relations with your father’s wife; it would dishonor your father. ⁹ You must not have sexual relations with your sister, either your father’s daughter or your mother’s daughter, whether she was born in the same home or elsewhere. ¹⁰ You must not have sexual relations with your son’s daughter or your daughter’s daughter, for that would shame your family. ¹¹ You must not have sexual relations with the daughter of your father’s wife, born to your father; she is your sister. ¹² You must not have sexual relations with your father’s sister; she is your father’s close relative. ¹³ You must not have sexual relations with your mother’s sister, for she is your mother’s close relative. ¹⁴ You must not dishonor your father’s brother by approaching his wife to have sexual relations with her; she is your aunt. ¹⁵ You must not have sexual relations with your daughter-in-law. She is your son’s wife; you are not to have sexual relations with her. ¹⁶ You must not have sexual relations with your brother’s wife; that would shame your brother. ¹⁷ You must not have sexual relations with both a woman and her daughter. You are not to marry her son’s daughter or her daughter’s daughter and have sexual relations with her. They are close relatives; it is depraved. ¹⁸ You must not take your wife’s sister as a rival wife and have sexual relations with her while your wife is still alive.
