Proverbs 26:10-12

International Standard Version

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.
¹² Do you see a man who is wise in his own opinion?
    There’s more hope for a fool than for him.
