Leviticus 18:1-15

Then the LORD spoke to Moses, saying, “Speak to the sons 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, nor are you to do what is done in the land of Canaan where I am bringing you; you shall not walk in their statutes. You are to perform My judgments and keep My statutes, to live in accord with them; I am the LORD your God. So you shall keep My statutes and My judgments, by which a man may live if he does them; I am the LORD. ‘None of you shall approach any blood relative of his to uncover nakedness; 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 are not to uncover her nakedness. You shall not uncover the nakedness of your father’s wife; it is your father’s nakedness. The nakedness of your sister, either your father’s daughter or your mother’s daughter, whether born at home or born outside, their nakedness you shall not uncover. The nakedness of your son’s daughter or your daughter’s daughter, their nakedness you shall not uncover; for their nakedness is yours. The nakedness of your father’s wife’s daughter, born to your father, she is your sister, you shall not uncover her nakedness. 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; 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.
