OET interlinear 2 KI 18:12

uW Translation Notes:

Note 1 topic: grammar-connect-words-phrases

עַ֣ל ׀ אֲשֶׁ֣ר

on/upon/above/on_account_of//he/it_went_in (Some words not found in UHB: on/upon/above/on_account_of//he/it_went_in which/who not obey to,the_voice_of YHWH God_of,their and,they_had_transgressed DOM covenant_of,his DOM all/each/any/every which/who commanded Mosheh servant_of YHWH and=not listen and=not they_had_acquired )

Here the word For introduces not a reason but an explanation. The author does not mean that the king of Assyria did the things he described in the previous verse because of the things he describes in this verse. He is explaining that the things in the previous verse happened because of the things in this verse. It may be helpful to clarify this for your readers. The UST models one way to do that.

Note 4 topic: figures-of-speech / parallelism

וְ⁠לֹ֥א שָׁמְע֖וּ וְ⁠לֹ֥א עָשֽׂוּ

and=not and=not (Some words not found in UHB: on/upon/above/on_account_of//he/it_went_in which/who not obey to,the_voice_of YHWH God_of,their and,they_had_transgressed DOM covenant_of,his DOM all/each/any/every which/who commanded Mosheh servant_of YHWH and=not listen and=not they_had_acquired )

Since, in this context, the term listen means “obey,” these two phrases mean basically the same thing. The second emphasizes the meaning of the first by repeating the same idea with different words. If it would be helpful to your readers, you could combine them and express the emphasis in another way. Alternate translation: [and they did not obey him at all]
