18. Like a house in ruins is wisdom to a fool;to the stupid, knowledge is incomprehensible chatter.
19. To the senseless, education is fetters on the feet,like manacles on the right hand.
20. Fools raise their voice in laughter,but the prudent at most smile quietly.
21. Like a gold ornament is education to the wise,like a bracelet on the right arm.
22. A fool steps boldly into a house,while the well-bred are slow to make an entrance.
23. A boor peeps through the doorway of a house,but the educated stay outside.
24. It is rude for one to listen at a door;the discreet person would be overwhelmed by the disgrace.
25. The lips of the arrogant talk of what is not their concern,but the discreet carefully weigh their words.
26. The mind of fools is in their mouths,but the mouth of the wise is in their mind.
27. When the godless curse their adversary,they really curse themselves.
28. Slanderers sully themselves,and are hated by their neighbors.
