Then follows a gleam of hope, like a rainbow spanning the waterfall. With the alternation of mood already noticed as characteristic, the singer looks forward, even from the midst of overwhelming seas of trouble, to a future day when God will give His angel, Mercy or Loving-kindness, charge concerning him and draw him out of many waters. That day of extrication will surely be followed by a night of music and of thankful prayer (for supplication is not the only element in prayer) to Him who by His deliverance has shown Himself to be the "God of" the rescued man's "life." The epithet answers to that of the former part, "the living God," from which it differs by but one additional letter. He who has life in Himself is the Giver and Rescuer of our lives, and to Him they are to be rendered in thankful sacrifice. Once more the contending currents meet in vv. 9 and 10, in the former of which confidence and hope utter themselves in the resolve to appeal to God and in the name given to Him as "my Rock"; while another surge of despondency breaks, in the question in which the soul interrogates God, as the better self had interrogated her, and contrasts almost reproachfully God's apparent forgetfulness, manifested by His delay in deliverance, with her remembrance of Him. It is not a question asked for enlightenment's sake, but is an exclamation of impatience, if not of rebuke. Ver. 10 repeats the enemies' taunt, which is there represented as like crushing blows which broke the bones. And then once more above this conflict of emotion soars the clear note of the refrain, summoning to self-command, calmness, and unfaltering hope.
