Proverbs 17:3-5

World English Bible

³ The refining pot is for silver, and the furnace for gold,
    but Yahweh tests the hearts.
⁴ An evildoer heeds wicked lips.
    A liar gives ear to a mischievous tongue.
⁵ Whoever mocks the poor reproaches his Maker.
    He who is glad at calamity shall not be unpunished.
