Proverbs 16:22

²⁰ He that handleth a matter wisely shall find good: and whoso trusteth in the LORD, happy is he.

²¹ The wise in heart shall be called prudent: and the sweetness of the lips increaseth learning.

Understanding is a wellspring of life unto him that hath it: but the instruction of fools is folly.

²³ The heart of the wise teacheth his mouth, and addeth learning to his lips.

²⁴ Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.
