John Calvin Commentary Psalms 34:6

"This poor man cried, and Jehovah heard him, And saved him out of all his troubles." — Psalms 34:6 (ASV)

This poor man cried, and Jehovah heard him. David here introduces all the godly speaking of himself, to express more emphatically how much weight there is in his example to encourage them. This poor man cried, they say; therefore God invites all the poor to cry to him. They contemplate in David what belongs to the common benefit of all the godly; for God is as willing and ready today to hear all the afflicted who direct their sighs, wishes, and cries to him with the same faith, as he was then to hear David.
