Imamat 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 

Imamat 18:17

18:17 You must not have sexual intercourse with both a woman and her daughter; you must not take as wife either her son’s daughter or her daughter’s daughter to have intercourse with them. ⁴  They are closely related to her ⁵  – it is lewdness. ⁶ 

[18:9]  ¹ tn Heb “the daughter of your father or the daughter of your mother.”

[18:9]  ² tn Heb “born of house or born of outside.” CEV interprets as “whether you grew up together or not” (cf. also TEV, NLT).

[18:9]  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.

[18:9]  tn For a smooth English translation “either of” was added.

[18:17]  ⁴ tn Heb “You must not uncover the nakedness of both a woman and her daughter; the daughter of her son and the daughter of her daughter you must not take to uncover her nakedness.” Translating “her” as “them” provides consistency in the English. In this kind of context, “take” means to “take in marriage” (cf. also v. 18). The LXX and Syriac have “their nakedness,” referring to the nakedness of the woman’s granddaughters, rather than the nakedness of the woman herself.

[18:17]  ⁵ tc Heb “they are her flesh.” The LXX reads “your” here (followed by NRSV). If the LXX reading were followed by the present translation, the result would be “They are closely related to you.”

[18:17]  ⁶ tn The term rendered “lewdness” almost always carries a connotation of cunning, evil device, and divisiveness (cf. HALOT 272 s.v. I זִמָּה 2, “infamy”), and is closely associated with sexual and religious infidelity (cf., e.g., Lev 19:29; 20:14; Job 31:11; Jer 13:27; Ezek 16:27; 22:9). Recent English versions differ on how they handle this: NAB “would be shameful”; CEV “would make you unclean”; NIV “wickedness”; NLT “horrible wickedness”; NRSV “depravity”; TEV “incest.”
