Proverbs 26:2-4

Lexham English Bible

² Like the sparrow is to fluttering and like the swallow is to flying,
    so an undeserved curse does not go forth.
³ A whip for the horse, a bridle for the donkey,
    and a rod for the back of fools.
⁴ Do not answer a fool according to his folly
    lest you become like him—even you.
