John Gill's Bible Commentary Ver. 4. The words of a man’s mouth [are as] deep waters , etc.] The words of a great and mighty man; of an excellent and valuable man, as Jarchi; or of a wise man, as Aben Ezra. The doctrines which such a man has imbibed, and his heart is full of and his mouth utters, are like to “waters”, pure, purifying, and refreshing; to “deep waters”, which make no noise, and cannot be easily fathomed: such are the deep mysteries of grace, the wisdom of God in a mystery, spoken among them that are perfect; of which a good man makes no boast, but humbly declares; out of the abundance of his heart, his mouth speaks; [and] the wellspring of wisdom [as] a flowing brook ; there is a spring of spiritual wisdom and knowledge in him; a well of living water, springing up unto everlasting life; and from thence it flows freely and constantly; communicating itself liberally unto others, and ministering grace to the hearers, for their edification.
Matthew Henry Commentary
Verses 4 - The well-spring of wisdom in the heart of a believer, continuall supplies words of wisdom.
