"But it is the spirit in a man, the breath of the Almighty, that gives him understanding."
Elihu is one of those heroes of the Bible you really don't hear much about. When no one else could show Job his error (and yet condemned him anyway), Elihu spoke wisdom according to the spirit given to him from God. Scripture says the Elihu was angry with Job for trying to justify himself instead of God. Instead of trusting in God's righteousness, Job questions God's very motives. Who can form a case against God? What accusations can they use? Truly if not for the lies of the Pharisees, Jesus would not have died for even Pilate found no fault with him.
Elihu is an inspiration to young people like me that we too can speak the Lord's wisdom. There is no wisdom that we could possess that doesn't come from God. Elihu speaks brilliantly concerning the Problem of Evil and the entire story is theodicy, that is a defense of God's good name in face of the problem of evil. However, some use this exact story to condemn God for what He did to Job and they make the same mistake. This is what can happen when you do not know the whole story.
If there is anything you should read in Job, it would be what Elihu has to say to Job. Had I more words to write I would write them for you, but alas the wisdom of the Bible surpasses the constraints of this blog. If you lack wisdom, you have no farther to look than the Word of God, the very breath of life that sustains us all.
