15. If a man of knowledge hear a wise word, He will commend it, and add to it: The dissolute man hears it, and it displeases him, And he puts it away behind his back.
16. The discourse of a fool is like a burden in the way; But grace shall be found on the lips of the wise.
17. The mouth of the prudent man shall be sought for in the congregation; And they will ponder his words in their heart.
18. As a house that is destroyed, so is wisdom to a fool; And the knowledge of an unwise man is as talk without sense.
19. Instruction is as fetters on the feet of an unwise man, And as manacles on the right hand.
20. A fool lifts up his voice with laughter; But a clever man will scarce smile quietly.
21. Instruction is to a prudent man as an ornament of gold, And as a bracelet upon his right arm.
