Leviticus 18:6-18

⁶ None of you shall approach to any that are near of kin to him, to uncover [their] nakedness: I am Jehovah. ⁷ The nakedness of thy father, even 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 the daughter of thy mother, whether born at home, or born abroad, even their nakedness thou shalt not uncover. ¹⁰ The nakedness of thy son's daughter, or of thy daughter's daughter, even their nakedness thou shalt not uncover: for theirs is thine own 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 Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman. ¹³ Thou shalt not uncover the nakedness of thy mother's sister: for she is thy mother's near kinswoman. ¹⁴ Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt. ¹⁵ Thou shalt not uncover the nakedness of thy daughter-in-law: she is thy son's wife; thou shalt not uncover her nakedness. ¹⁶ Thou shalt not uncover the nakedness of thy brother's wife: it is thy brother's nakedness. ¹⁷ Thou shalt not uncover the nakedness of a woman and her daughter; thou shalt not take her son's daughter, or her daughter's daughter, to uncover her nakedness; they are near kinswomen: it is wickedness. ¹⁸ And thou shalt not take a wife to her sister, to be a rival [to her], to uncover her nakedness, besides the other in her life-time.
