John Gill, on Prov 20:15

“There is gold, and a multitude of jewels: but the lips of knowledge are a precious vessel.”

“There is gold, and a multitude of rubies,.... A man may have a large quantity of either, or of both of thorn, as some men have; for there is much of them in the world, not only in mines and quarries, but in the houses and cabinets of men; but the lips of knowledge are a precious jewel; knowledge even of things natural, and a gift of elocution to express it by, are a rare jewel, and much more precious than gold and rubies, than a multitude of them; these are not to be mentioned with it, it is not equalled by them, it is greatly superior to them; see Job 28:12; and much more spiritual knowledge, and a capacity of expressing that to the edification of others; and especially Christ, the Wisdom of God, and the knowledge of him, who is more precious than rubies, and all desirable things, in comparison of which all things are loss and dung, Pro 3:14.”
