Albert Barnes Commentary Job 15:22

"He believeth not that he shall return out of darkness, And he is waited for of the sword." — Job 15:22 (ASV)

He believeth not that he shall return out of darkness - Darkness is used in the Bible, as elsewhere, to denote calamity. The meaning here is that the wicked man does not have confidence (יאמין לא lo' ya'amı̂yn) that he will return safely from impending danger.

He is in constant dread of assassination or of some fearful evil. He is never secure; his mind is never calm; he lives in constant dread. This is still an accurate description of a man with a guilty conscience, for such a man lives in constant fear and never feels any security that he is safe.

And he is waited for of the sword - That is, he is destined for the sword. Gesenius.
