Charles H. Spurgeon on Psalms 34:6

This poor man cried. Here he returns to his own case. He was poor indeed, and so utterly friendless that his life was in great jeopardy; but he cried in his heart to the protector of his people and found relief. His prayer was a cry, for brevity and bitterness, for earnestness and simplicity, for artlessness and grief; it was a poor man's cry, but it was none the less powerful with heaven, for the Lord heard him, and to be heard of God is to be delivered; and so it is added that the Lord saved him out of all his troubles. At once and altogether David was clean rid of all his woes. The Lord sweeps our griefs away as men destroy a hive of hornets, or as the winds clear away the mists. Prayer can clear us of troubles as easily as the Lord made riddance of the frogs and flies of Egypt when Moses entreated him. This verse is the psalmist's own personal testimony: he being dead yet speaketh. Let the afflicted reader take heart and be of good courage.
