Proverbs 17:2-4

World English Bible

² A servant who deals wisely will rule over a son who causes shame,
    and shall have a part in the inheritance among the brothers.
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.
