Ezekiel 22:11

[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.

[20:12]  ⁴ tn Heb “but also.”

[27:2]  ⁵ tn The word “River” is not in the Hebrew text but has been supplied in the translation for clarity.

[27:2]  ⁶ tn Heb “plaster” (so KJV, ASV; likewise in v. 4). In the translation “cover” has been used for stylistic reasons.

[22:11]  ⁷ tn Heb “a man.”

[22:11]  ⁸ tn The verb is the same one used in verse 10b and suggests forcible sexual violation of the woman.

[22:11]  ⁹ sn Sexual relations with one’s half-sister may be primarily in view here. See Lev 18:9; 20:17.
