¹⁰The 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.

¹¹The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.

¹²Thou shalt not uncover the nakedness of thy father’s sister: she is thy father’s near kinswoman.
