A dreadful sound is in his ears Even when he feels no evil, he is tormented with perpetual fears and expectations of it, from a consciousness of his own guilt, and a sense of God's all-seeing eye and righteous judgment. In prosperity the destroyer shall come upon him In the most peaceable and prosperous time, he is not in safety, nor does he think himself to be so, but he is always fearing some one or other will injure him as he has injured others; and that some enemy will invade and destroy him suddenly and unexpectedly. He knows both heaven and earth are incensed against him; and that he has done nothing to make his peace with either, and, therefore, thinks every one that meets him will slay him. A guilty conscience represents to the sinner a flaming sword turning every way, and himself inevitably running upon it. He believeth not that he shall return out of darkness When he falls into trouble he despairs of deliverance, by reason of his guilty conscience. And he is waited for of the sword Besides the calamity which is upon him, he is in constant expectation of greater. The sword is used for any grievous affliction.
