OET interlinear 2 SAM 17:14

uW Translation Notes:

Note 1 topic: grammar-connect-words-phrases

וַ⁠יהוָ֣ה

and,Yahweh

Here the word For introduces not a reason but an explanation. Alternate translation: [This happened because]

Note 2 topic: figures-of-speech / metaphor

לְ⁠הָפֵ֞ר

to,frustrate

See how you translated the similar expression in 15:34. Alternate translation: [to counter]

Note 3 topic: figures-of-speech / explicit

אֶת־עֲצַ֤ת אֲחִיתֹ֨פֶל֙ הַ⁠טּוֹבָ֔ה

DOM counsel_of ʼAḩītofel (the),good

The author does not mean that it was morally good for Ahithophel to have recommended launching a sudden attack in order to kill David. He means that Ahithophel’s counsel would have been “good” for Absalom in the sense that it would have been more effective in defeating David. You could translate the term that way if that would be helpful to your readers. Alternate translation: [the counsel of Ahithophel that would have been more effective]

Note 4 topic: writing-pronouns

לְ⁠בַ⁠עֲב֗וּר הָבִ֧יא יְהוָ֛ה אֶל־אַבְשָׁל֖וֹם אֶת־הָ⁠רָעָֽה

Since the author has already mentioned Yahweh earlier in the sentence, it may be more natural in your language to refer to him with a pronoun here. Alternate translation: [so that he could bring harm to Absalom]
