Proverbs 18:4 The words of a man’s mouth are as deep waters, and the wellspring of wisdom as a flowing brook. 

‘As deep waters.’ This phrase likely refers to the depth and mystery that can reside in human speech, especially in the speech of a thoughtful or wise person. “Deep waters” (Hebrew: mayim ʿamūqīm) suggests profound insight, layers of meaning, or even hidden motives that take discernment to understand.

‘The wellspring of wisdom…’ The second part of the verse shifts from depth to refreshment and clarity. A “wellspring” (or fountain) implies a constant source of wisdom, in this case, that flows like a “brook” (stream), bringing life, nourishment, and guidance. This wisdom is not stagnant or hidden but active, generous, and sustaining.

The speech of a wise man is both deep and nourishing. Some words require discernment to grasp their depth, while others are like a bubbling spring, clear, refreshing, and constantly flowing.

We should aim to cultivate speech that is wise, thoughtful, and beneficial, not shallow or reactionary. True wisdom isn’t just knowing what to say, but offering words that both edify and refresh those who hear. It’s also a reminder to listen carefully, some speech holds treasure beneath the surface.
