Orthodox Jewish Bible

⁹ The nakedness of thy achot (sister), the bat of thy av, or bat of thy em, whether she be moledet bais (born at home), or moledet chutz (born outside), even their nakedness thou shalt not uncover.

¹⁰ The nakedness of the bat of thy ben, or the bat of thy bat, even their nakedness thou shalt not uncover; for theirs is thine own nakedness.

¹¹ The nakedness of the bat of the wife of thy av, begotten of thy av, she is thy achot (sister), thou shalt not uncover her nakedness.
