What does Proverbs 3:15 mean?

In this verse Solomon continues to describe the value of wisdom. This continues the poetic representation of wisdom as a woman (Proverbs 1:20; 3:14). He says wisdom is more precious than jewels, and nothing anyone might desire can compare with wisdom. Proverbs uses the term wisdom in reference to something more than mere intelligence, or knowledge. Biblical wisdom is the ability to apply knowledge in a godly way. That capacity to follow God's will is incredibly valuable—more so than any material possession ever would be.

The Hebrew word translated "jewels" in the ESV is pe'niy'yim, which more or less means "pearls," but can also be applied to all kinds of precious gems. As of this writing, an emerald-and-diamond ring associated with the Rockefeller family carries an estimated value of $5.5 million in United States dollars. A stone known as the Oppenheimer Blue diamond carries a value more than $57.5 million, and the famous Hope Diamond is estimated to be worth $250 million. Nevertheless, none of these gems are as valuable as wisdom.

Furthermore, this Scripture affirms that nothing a person can desire can compare with wisdom. That includes all possessions, accolades, and luxuries. A person may desire fame or fortune, but wisdom is far better. Even ownership of the world's highest priced mansion, automobile, yacht, or private jet cannot compare with the value of wisdom. A truly wise person can enjoy fellowship with God now and forever as well as eternal rewards, whereas a worldly-wise person without God may surround himself with luxuries, but he has nothing of eternal value.
