C.H. Spurgeons's The Treasury of David
Verse 18. I will give thee thanks in the great congregation. Notable deliverances must be recorded, and their fame emblazoned. All the saints should be informed of the Lord's goodness. The theme is worthy of the largest assembly, the experience of a believer is a subject fit for an assembled universe to hear of. Most men publish their griefs, good men should proclaim their mercies. I will praise thee among much people. Among friends and foes will I glorify the God of my salvation. Praise -- personal praise, public praise, perpetual praise -- should be the daily revenue of the King of heaven. Thus, for the second time, David's prayer ends in praise, as indeed all prayers should.
