Imamat 18:11

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 

Imamat 18:14

18:14 You must not expose the nakedness of your father’s brother; you must not approach his wife to have sexual intercourse with her. ²  She is your aunt. ³ 

[18:11]  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.

[18:14]  ² tn Heb “you must not draw near to his wife.” In the context this refers to approaching one’s aunt to have sexual intercourse with her, so this has been specified in the translation for clarity.

[18:14]  ³ tn As in v. 12 (see the note there), some mss and versions have “because she is your aunt.”
