Proverbs 20:15 - Joseph Benson’s Commentary on the Old and New Testaments

There is gold, &c. Namely, in the world, in divers persons' hands, by whom it is much prized; but the lips of knowledge Wise speeches, proceeding from a well-informed and upright mind, are a precious jewel Are of far greater worth, both to him that utters them, and to those that receive and improve them to their own benefit.
