Leviticus 18:6-18

⁶ No one shall approach to any that is his near relation, to uncover his nakedness: I am Jehovah. ⁷ The nakedness of thy father, and the nakedness of thy mother, shalt thou not uncover: she is thy mother: thou shalt not uncover her nakedness. ⁸ The nakedness of thy father's wife shalt thou not uncover: it is thy father's nakedness. ⁹ The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, born at home, or born abroad—their nakedness shalt thou not uncover. ¹⁰ The nakedness of thy son's daughter, or of thy daughter's daughter—their nakedness shalt thou not uncover; for theirs is thy nakedness. ¹¹ The nakedness of thy father's wife's daughter, begotten of thy father: she is thy sister: thou shalt not uncover her nakedness. ¹² The nakedness of thy father's sister shalt thou not uncover: she is thy father's near relation. ¹³ The nakedness of thy mother's sister shalt thou not uncover; for she is thy mother's near relation. ¹⁴ The nakedness of thy father's brother shalt thou not uncover; thou shalt not approach his wife: she is thine aunt. ¹⁵ The nakedness of thy daughter-in-law shalt thou not uncover: she is thy son's wife; thou shalt not uncover her nakedness. ¹⁶ The nakedness of thy brother's wife shalt thou not uncover: it is thy brother's nakedness. ¹⁷ The nakedness of a woman and her daughter shalt thou not uncover; thou shalt not take her son's daughter, nor her daughter's daughter, to uncover her nakedness: they are her near relations: it is wickedness. ¹⁸ And thou shalt not take a wife to her sister, to vex her, to uncover her nakedness beside her, during her life.
