Proverbs 20:15-17

New Revised Standard Version, Anglicised

¹⁵ There is gold, and abundance of costly stones;
    but the lips informed by knowledge are a precious jewel.
¹⁶ Take the garment of one who has given surety for a stranger;
    seize the pledge given as surety for foreigners.
¹⁷ Bread gained by deceit is sweet,
    but afterwards the mouth will be full of gravel.
