Приповісті 20:15

15 There is indeed gold, and many pearls; But a precious treasure are lips full of knowledge. In order to find a connection between this proverb and that which precedes, we need only be reminded of the parable of the merchantman who sought goodly pearls, Mat 13:45. The proverb rises to a climax: there is gold, and there are pearls in abundance, the one of which has always a higher value than the other; but intelligent lips are above all such jewels - they are a precious treasure, which gold and all pearls cannot equal. In a similar manner the N.T. places the one pearl above the many goodly pearls. So might דעת (chokma) be called the pearl above all pearls (Pro 3:15; Pro 8:11); but the lips as the organ of knowledge are fittingly compared with a precious vessel, a vessel of more precious substance than gold and pearls are.

The lips of knowledge (a good understanding to guide the lips and a good elocution to diffuse the knowledge) are to be preferred far before gold, and pearl, and rubies; for, 1. They are more rare in themselves, more scarce and hard to be got. There is gold in many a man's pocket that has no grace in his heart. In Solomon's time there was plenty of gold (Kg1 10:21) and abundance of rubies; every body wore them; they were to be bought in every town. But wisdom is a rare thing, a precious jewel; few have it so as to do good with it, nor is it to be purchased of the merchants. 2. They are more enriching to us and more adorning. They make us rich towards God, rich in good works, Ti1 2:9, Ti1 2:10. Most people are fond of gold, and a ruby or two will not serve, they must have a multitude of them, a cabinet of jewels; but he that has the lips of knowledge despises these, because he knows and possesses better things.
