Proverbs 27:2-4

New Revised Standard Version, Anglicised

² Let another praise you, and not your own mouth—
    a stranger, and not your own lips.
³ A stone is heavy, and sand is weighty,
    but a fool’s provocation is heavier than both.
⁴ Wrath is cruel, anger is overwhelming,
    but who is able to stand before jealousy?
