Charles Ellicott Commentary Psalms 39:7

"And now, Lord, what wait I for? My hope is in thee." — Psalms 39:7 (ASV)

And now, Lord ... —“If such is man’s condition, what,” says the psalmist, “is my expectation?” We seem to hear the deep sigh with which the words are uttered; and we must remember that the poet can turn for comfort to no hope of immortality. That had not yet dawned. The thought of God’s mercy, and the hope of his own moral deliverance, these form the ground of his noble elevation above the oppressive sense of human frailty. The Septuagint and Vulgate render it very expressively:

“And now what is my expectation? Is it not the Lord?
And my substance is with you.”
