Proverbs 16:21-24

²¹The wise in heart shall be called prudent: and he that is sweet in words shall attain to greater things.

²²Knowledge is a fountain of life to him that possesseth it: the instruction of fools is foolishness.

²³The heart of the wise shall instruct his mouth: and shall add grace to his lips.

²⁴Well ordered words are as a honeycomb: sweet to the soul, and health to the bones.
