Leviticus 18:1-20

Then the LORD spoke to Moses, saying, “Speak to the children of Israel, and say to them: ‘I am the LORD your God. According to the doings of the land of Egypt, where you dwelt, you shall not do; and according to the doings of the land of Canaan, where I am bringing you, you shall not do; nor shall you walk in their ordinances. You shall observe My judgments and keep My ordinances, to walk in them: I am the LORD your God. You shall therefore keep My statutes and My judgments, which if a man does, he shall live by them: I am the LORD. ‘None of you shall approach anyone who is near of kin to him, to uncover his nakedness: I am the LORD. The nakedness of your father or the nakedness of your mother you shall not uncover. She is your mother; you shall not uncover her nakedness. The nakedness of your father’s wife you shall not uncover; it is your father’s nakedness. The nakedness of your sister, the daughter of your father, or the daughter of your mother, whether born at home or elsewhere, 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 theirs is your own nakedness. The nakedness of your father’s wife’s daughter, begotten by 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 near of kin to your father. You shall not uncover the nakedness of your mother’s sister, for she is near of kin to your mother. 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. You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness. You shall not uncover the nakedness of a woman and her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness. They are near of kin to her. It is wickedness. Nor shall you take a woman as a rival to her sister, to uncover her nakedness while the other is alive. ‘Also you shall not approach a woman to uncover her nakedness as long as she is in her customary impurity. Moreover you shall not lie carnally with your neighbor’s wife, to defile yourself with her.
