Most commentators agree that this verse praises the speech of a wise person. Their words are like 'deep waters'—profound and not easily fathomed. Simultaneously, they come from a 'wellspring of wisdom' that is like a 'flowing brook'—clear, refreshing, and life-giving. Scholars like Ellicott and Gill explain that both phrases positively describe the rich and beneficial nature of words that flow from a heart full of wisdom.
