Leviticus 18:6-18

Laws of Sexual Relations

18:6 “‘No man is to approach any close relative to have sexual intercourse with her. I am the Lord. 18:7 You must not expose your father’s nakedness by having sexual intercourse with your mother. She is your mother; you must not have intercourse with her. 18:8 You must not have sexual intercourse with your father’s wife; she is your father’s nakedness. 18:9 You must not have sexual intercourse with your sister, whether she is your father’s daughter or your mother’s daughter, whether she is born in the same household or born outside it; you must not have sexual intercourse with either of them. 18:10 You must not expose the nakedness of your son’s daughter or your daughter’s daughter by having sexual intercourse with them, because they are your own nakedness. 18:11 You must not have sexual intercourse with the daughter of your father’s wife born of your father; she is your sister. You must not have intercourse with her. 18:12 You must not have sexual intercourse with your father’s sister; she is your father’s flesh. 18:13 You must not have sexual intercourse with your mother’s sister, because she is your mother’s flesh. 18:14 You must not expose the nakedness of your father’s brother; you must not approach his wife to have sexual intercourse with her. She is your aunt. 18:15 You must not have sexual intercourse with your daughter-in-law; she is your son’s wife. You must not have intercourse with her. 18:16 You must not have sexual intercourse with your brother’s wife; she is your brother’s nakedness. 18:17 You must not have sexual intercourse with both a woman and her daughter; you must not take as wife either her son’s daughter or her daughter’s daughter to have intercourse with them. They are closely related to her – it is lewdness. 18:18 You must not take a woman in marriage and then marry her sister as a rival wife while she is still alive, to have sexual intercourse with her.
