Proverbs 16:20-22

Amplified Bible

²⁰ 
He who pays attention to the word [of God] will find good,
And blessed (happy, prosperous, to be admired) is he who trusts [confidently] in the Lord.
²¹ 
The wise in heart will be called understanding,
And sweet speech increases persuasiveness and learning [in both speaker and listener].
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.
