Leviticus 18:9

18:9 You must not have sexual intercourse with your sister, whether she is your father’s daughter or your mother’s daughter, ¹  whether she is born in the same household or born outside it; ²  you must not have sexual intercourse with either of them. ³ 

¹ tn Heb “the daughter of your father or the daughter of your mother.”

² tn Heb “born of house or born of outside.” CEV interprets as “whether you grew up together or not” (cf. also TEV, NLT).

³ tc Several medieval Hebrew mss, Smr, LXX, and Syriac have “her nakedness” rather than “their nakedness,” thus agreeing with singular “sister” at the beginning of the verse.
