Proverbs 26:9-11

Common English Bible

⁹ Like a thorny bush in the hand of a drunk,
    so is a proverb in the mouth of fools.
¹⁰ Like an archer who wounds someone randomly,
    so is one who hires a fool or a passerby.
¹¹ Like a dog that returns to its vomit,
    so a fool repeats foolish mistakes.
