Proverbs 16:21-23

Amplified Bible, Classic Edition

²¹ The wise in heart are called prudent, understanding, and knowing, and winsome speech increases learning [in both speaker and listener].

²² Understanding is a wellspring of life to those who have it, but to give instruction to fools is folly.

²³ The mind of the wise instructs his mouth, and adds learning and persuasiveness to his lips.
