Leviticus 18:1-15

Then the LORD spoke to Moses, saying, “Speak to the children of Israel and say to them, ‘I am the LORD your God. You shall not do what is done in the land of Egypt where you lived, and you shall not do what is done in the land of Canaan where I am bringing you. You shall not follow their statutes (practices, customs). You are to follow My judgments (precepts, ordinances) and keep My statutes and live by them. I am the LORD your God. So you shall keep My statutes and My judgments, by which, if a person keeps them, he shall live; I am the LORD. [Luke 10:25-28; Rom 10:4, 5; Gal 3:12] ‘No one shall approach any blood relative of his to uncover nakedness (have intimate relations). I am the LORD. You shall not uncover the nakedness of your father, that is, the nakedness of your mother. She is your mother. You shall not uncover her nakedness. You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. You shall not uncover the nakedness of your sister, either the daughter of your father or of your mother, whether born at home or born elsewhere. You shall not uncover the nakedness of your son’s daughter or your daughter’s daughter; their nakedness you shall not uncover, for they are your own nakedness [that is, your own descendants]. You shall not uncover the nakedness of your father’s wife’s daughter; born to your father, she is your sister. You shall not uncover the nakedness of your father’s sister; she is your father’s blood relative. You shall not uncover the nakedness of your mother’s sister, for she is your mother’s blood relative. You shall not uncover the nakedness of your father’s brother’s wife; you shall not approach his wife; she is your aunt. You shall not uncover the nakedness of your daughter-in-law; she is your son’s wife. You shall not uncover her nakedness.
