Charles H. Spurgeon on Psalms 32:6

The floods of great waters. The afflictions of the faithful are likened to waters. Fire and water have no mercy, we say. But of the two water is the worst. For any fire may be quenched with water; but the force of water, if it begins to be violent, cannot by any power of man, be resisted. But these our tribulations which are waters are "many waters." Our common proverb is, "Seldom comes sorrow alone:" but as waters come rolling and waving many together, so the miseries of this life. Thomas Playfere.
