Leviticus 18:10-12

New Revised Standard Version, Anglicised

¹⁰ You shall not uncover the nakedness of your son’s daughter or of your daughter’s daughter, for their nakedness is your own nakedness. ¹¹ You shall not uncover the nakedness of your father’s wife’s daughter, begotten by your father, since she is your sister. ¹² You shall not uncover the nakedness of your father’s sister; she is your father’s flesh.
