Job 15:22

That he shall return out of darkness - If he take but a few steps in the dark, he expects the dagger of the assassin. This appears to be the only meaning of the place. Some think the passage should be understood to signify that he has no hope of a resurrection; he can never escape from the tomb. This I:doubt: in the days of the writer of this book, the doctrine of a future judgment was understood in every part of the East where the knowledge of the true God was diffused.

He believeth not that he shall return out of darkness - Darkness is used in the Bible, as elsewhere, to denote calamity; and the meaning here is, that the wicked man has not confidence (יאמין לא lo' ya'amı̂yn), that he shall 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.

15:22 Believeth not - When he falls into trouble, he despairs of deliverance, by reason of his guilty conscience. Waited for - Besides the calamity which is upon him, he is in constant expectation of greater; the sword is used for any grievous affliction.
