21:12 He that is not wise will not be taught: but there is a wisdom which multiplieth bitterness.
21:13 The knowledge of a wise man shall abound like a flood: and his counsel is like a pure fountain of life.
21:14 The inner parts of a fool are like a broken vessel, and he will hold no knowledge as long as he liveth.
21:15 If a skilful man hear a wise word, he will commend it, and add unto it: but as soon as one of no understanding heareth it, it displeaseth him, and he casteth it behind his back.
21:16 The talking of a fool is like a burden in the way: but grace shall be found in the lips of the wise.
21:17 They enquire at the mouth of the wise man in the congregation, and they shall ponder his words in their heart.
21:18 As is a house that is destroyed, so is wisdom to a fool: and the knowledge of the unwise is as talk without sense.
21:19 Doctrine unto fools is as fetters on the feet, and like manacles on the right hand.
21:20 A fool lifteth up his voice with laughter; but a wise man doth scarce smile a little.
21:21 Learning is unto a wise man as an ornament of gold, and like a bracelet upon his right arm.
