Proverbs 27:2-4

New International Reader's Version

² Let another person praise you, and not your own mouth.
    Let an outsider praise you, and not your own lips.

³ Stones are heavy, and sand weighs a lot.
    But letting a foolish person make you angry is a heavier load than both of them.

⁴ Anger is mean, and great anger overpowers you.
    But who can face jealousy?
