⁹ Like a thorn in the hand of a drunkard,
    so is a proverb in the mouth of a fool.
¹⁰ Like an archer who shoots at random and injures everyone,
    so is a person who hires a fool or someone off the street.^[a]
11 Like a dog who goes back to his own vomit,^[b]
    so is a fool who always returns to his foolishness.
