[18:19] 1 tn The two words נִין (nin, “offspring”) and נֶכֶד (nekhed, “posterity”) are always together and form an alliteration. This is hard to capture in English, but some have tried: Moffatt had “son and scion,” and Tur-Sinai had “breed or brood.” But the words are best simply translated as “lineage and posterity” or as in the NIV “offspring or descendants.”
[18:19] 2 tn Heb “in his sojournings.” The verb גּוּר (gur) means “to reside; to sojourn” temporarily, without land rights. Even this word has been selected to stress the temporary nature of his stay on earth.
[21:11] 4 tn Heb “they extend against you harm.” The perfect verbal forms in v. 11 are taken as generalizing, stating factually what the king’s enemies typically do. Another option is to translate with the past tense (“they intended…planned”).
