Proverbs 16:20-23

²⁰The learned in word shall find good things: and he that trusteth in the Lord is blessed.

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.
