Proverbs 17:3-5

New Catholic Bible

³ The crucible is for silver and the furnace is for gold,
    but it is the Lord who tests the heart.
⁴ An evildoer listens eagerly to wicked lips,
    and a liar pays heed to a slanderous tongue.
⁵ Anyone who mocks the poor insults their Creator;^[a]
    whoever gloats at another’s distress will not go unpunished.
