Proverbs 20:14-16

Complete Jewish Bible

¹⁴ “Really bad stuff!” says the buyer [to the seller];
    then he goes off and brags [about his bargain].

¹⁵ A person may have gold and a wealth of pearls,
    but lips informed by knowledge are a precious jewel.

¹⁶ Seize his clothes, because he guaranteed a stranger’s loan;
    take them as security for that unknown woman.
