This is a chapter about wisdom. Job discussed what is wisdom and where it can be found.
v1-11: Job described men intelligent and ability to perform many words. Men know about to mine silver and iron, refined gold and smelt copper (v1-2). Men are able to explore places no one has never been before (v4). Bird and beasts do not know what is hidden under the earth (v7-8), but men were able to turn over rocks (v9), tunnels through rock (v10), and searches the sources of rivers. Job’s point is men are able to discover new things, men are smarter then any animals, men can create tools, use technology, but none of these is wisdom.
v12-20: Then Job ask a rhetorical questions, “But where can wisdom be found? Where does understanding dwell? (v12). “WHere then does wisdom come from? Where does understanding dwell? (v20)? Men think money is everything. Job said no amount of precious stone can purchase wisdom (v15-19).
v20-28: God alone understands the way to wisdom (v23). In NT, we are told that the Lord Jesus is wisdom (1 Cor. 1:24). In Him is hidden “all the treasures of wisdom and knowledge (Col 2:3). Job finally gave the answer to his own question: “The fear of the Lord, that is wisdom, and to shun evil is understanding.” The is exactly God’s comment for Job in Chapter 1 and 2.
