Proverbs 26:3-5

International Standard Version

³ A whip is for the horses,
    a bridle is for the donkey,
        a rod is for the back of fools.
⁴ Don’t answer a fool according to his foolishness,
    or you will be just like him.
⁵ Answer a fool according to his foolishness,
    or he will think himself to be wise.
