Leviticus 18:8-10

American Standard Version

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.
