Proverbs 16:22-24

Amplified Bible

²² 
Understanding (spiritual insight) is a [refreshing and boundless] wellspring of life to those who have it,
But to give instruction and correction to fools is foolishness.
²³ 
The heart of the wise instructs his mouth [in wisdom]
And adds persuasiveness to his lips.
²⁴ 
Pleasant words are like a honeycomb,
Sweet and delightful to the soul and healing to the body.
