OET interlinear 2 KI 9:20

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

וְ⁠הַ⁠מִּנְהָ֗ג

(Some words not found in UHB: and,he_reported the,watchman to=say he/it_came until to,them and=not coming_back and,the,driving [is]_like,the_driving_of Yēhūʼ/(Jehu) son_of Nimshiy that/for/because/then/when with,madness drives )

The watchman assumes that the king will understand that by the driving, he means the driving of the person to whom the two messengers spoke. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [and the driving of the person to whom the two messengers spoke]

Note 2 topic: grammar-connect-words-phrases

כִּ֥י

(Some words not found in UHB: and,he_reported the,watchman to=say he/it_came until to,them and=not coming_back and,the,driving [is]_like,the_driving_of Yēhūʼ/(Jehu) son_of Nimshiy that/for/because/then/when with,madness drives )

Here the word For introduces not a reason but an explanation. Alternate translation: [I say that because]

Note 3 topic: figures-of-speech / hyperbole

בְ⁠שִׁגָּע֖וֹן

(Some words not found in UHB: and,he_reported the,watchman to=say he/it_came until to,them and=not coming_back and,the,driving [is]_like,the_driving_of Yēhūʼ/(Jehu) son_of Nimshiy that/for/because/then/when with,madness drives )

The watchman is saying with madness as an overstatement for emphasis. If it would be helpful in your language, you could use a different way to express the emphasis. Alternate translation: [furiously]
