Proverbs 16:20-22

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. The wise in heart will be called understanding, And sweet speech increases persuasiveness and learning [in both speaker and listener]. 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.
