16:21 The one who is wise in heart is called discerning,
and kind speech increases persuasiveness.
16:22 Insight is like a life-giving fountain to the one who possesses it,
but folly leads to the discipline of fools.
16:23 A wise person’s heart makes his speech wise
and it adds persuasiveness to his words.
16:24 Pleasant words are like a honeycomb,
sweet to the soul and healing to the bones.
