Proverbs 26:9-11

International Standard Version

⁹ A thorn in the hand of a drunkard—
    that’s what a proverb quoted by a fool is.
¹⁰ An archer who shoots at anyone—
    is like someone who hires a fool or anyone who passes by.
¹¹ A dog that returns to its vomit
    is like a fool who reverts to his folly.
