Proverbs 20:15-17

World English Bible

¹⁵ There is gold and abundance of rubies,
    but the lips of knowledge are a rare jewel.
¹⁶ Take the garment of one who puts up collateral for a stranger;
    and hold him in pledge for a wayward woman.
¹⁷ Fraudulent food is sweet to a man,
    but afterwards his mouth is filled with gravel.
