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 

Leviticus 20:11

20:11 If a man has sexual intercourse with his father’s wife, he has exposed his father’s nakedness. ⁴  Both of them must be put to death; their blood guilt is on themselves. ⁵ 

Leviticus 20:21

20:21 If a man has sexual intercourse with ⁶  his brother’s wife, it is indecency. He has exposed his brother’s nakedness; ⁷  they will be childless.

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.

⁴ sn See the note on Lev 18:7 above.

⁵ tn See the note on v. 9 above.

⁷ tn Heb “takes.” The verb “to take” in this context means “to engage in sexual intercourse.”

⁸ sn See the note on Lev 18:7 above.
