Leviticus 18:6-18

⁶ You may not have sex connection with anyone who is a near relation: I am the Lord. ⁷ You may not have sex relations with your father or your mother: she is your mother, you may not take her. ⁸ And you may not have sex relations with your father's wife: she is your father's. ⁹ You may not take your sister, the daughter of your father or of your mother, wherever her birth took place, among you or in another country. ¹⁰ You may not have sex relations with your son's daughter or your daughter's daughter, for they are part of yourself; ¹¹ Or your father's wife's daughter, the child of your father, for she is your sister. ¹² You may not have sex connection with your father's sister, for she is your father's near relation. ¹³ You may not have sex connection with your mother's sister, for she is your mother's near relation. ¹⁴ You may not have sex relations with the wife of your father's brother, for she is of your family; ¹⁵ Or with your daughter-in-law, for she is your son's wife, and you may not take her. ¹⁶ You may not have sex relations with your brother's wife, for she is your brother's. ¹⁷ You may not take as wife a woman and her daughter, or her son's daughter or her daughter's daughter, for they are of one family: it is an act of shame. ¹⁸ And you may not take as wife a woman and at the same time her sister, to be in competition with her in her life-time.
