Leviticus 18:11

You must not have sexual intercourse with the daughter of your father’s wife born of your father; she is your sister. You must not have intercourse with her. ¹ 

"‘Do not have sexual relations with the daughter of your father’s wife, born to your father; she is your sister.

‘The nakedness of your father’s wife’s daughter, born to your father, she is your sister, you shall not uncover her nakedness.

Do not have sexual intercourse with the daughter of any of your father’s wives; she is your half sister.

"Don't have sex with the daughter of your father's wife born to your father. She is your sister.

Or your father’s wife’s daughter, the child of your father, for she is your sister.

You shall not uncover the nakedness of your father’s wife’s daughter, begotten by your father, since she is your sister.

‘The nakedness of your father’s wife’s daughter, begotten by your father––she is your sister––you shall not uncover her nakedness.

You must not have sexual intercourse with the daughter of your father’s wife born of your father; she is your sister. You must not have intercourse with her. ¹ 

¹ tn Heb “The nakedness of the daughter of your father’s wife born of your father, she is your sister; you must not uncover her nakedness.” That is, a half sister, the daughter of the man’s father by another wife, who is not the man’s mother, is to be considered a true sister. Therefore, the man must not have sexual intercourse with her.
