You shall not uncover the nakedness of your sister , your father’s daughter or your mother’s daughter , whether brought up in the family or in another home .

“‘Do not have sexual relations with your sister, either your father`s daughter or your mother`s daughter, whether she was born in the same home or elsewhere.

The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.
