OET interlinear JOB 7:9

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

כָּלָ֣ה עָ֭נָן וַ⁠יֵּלַ֑ךְ

(Some words not found in UHB: vanishes cloud and,it_has_gone yes/correct/thus/so goes_down shəʼōl not it_will_ascend )

Job could be: (1) saying that once a cloud disappears, it goes away forever. That same cloud will never again form in the sky. Alternate translation: [Once a cloud disappears, it goes away forever]; (2) using the similar expressions disappears and goes away together for emphasis. Alternate translation: [A cloud disappears entirely]

Note 2 topic: figures-of-speech / doublenegatives

לֹ֣א יַעֲלֶֽה

not (Some words not found in UHB: vanishes cloud and,it_has_gone yes/correct/thus/so goes_down shəʼōl not it_will_ascend )

If it would be clearer in your language, you could use a positive expression to translate this double negative that consists of the negative particle not and the verb ascend, which is contrary to the reality of life, according to Job here. Alternate translation: [remains there]
