Job 15:22 - Matthew Poole's English Annotations on the Holy Bible

i.e. When he falls into trouble, he despairs of God's mercy, and of deliverance, by reason of his guilty conscience; which he speaks with particular reflection upon Job, who would receive no comfort nor matter of hope. He is waited for of the sword, i.e. besides the calamity which is upon him, he is in constant expectation of further and greater miseries; for the sword is oft used for any grievous affliction, as Luke 2:35.
