9. Like a thorn that goes [without being felt] into the hand of a drunken man, so is a proverb in the mouth of a [self-confident] fool.
10. [But] like an archer who wounds all, so is he who hires a fool or chance passers-by.
11. As a dog returns to his vomit, so a fool returns to his folly.
12. Do you see a man wise in his own eyes and conceit? There is more hope for a [self-confident] fool than for him. [Prov. 29:20; Luke 18:11; Rom. 12:16; Rev. 3:17.]
