Darby's Bible Synopsis
In Psalm 13 the righteous is reduced to the lowest point of distress as far as evil from men goes. It is as if God had entirely and definitely forgotten him. His enemy was exalted over him, and he taking counsel in his heart; but then he cries looks to Jehovah to hear lest he should perish on the one hand, and his enemy on the other have to say he had prevailed. But he is heard, and sings to Jehovah, in whose mercy he had trusted, and who deals bountifully with him at last.
How long shall I take counsel in my soul, having sorrow in my heart daily? how long shall mine enemy be exalted over me?
Consider and hear me, O LORD my God: lighten mine eyes, lest I sleep the sleep of death;
Lest mine enemy say, I have prevailed against him; and those that trouble me rejoice when I am moved.
