v1-2: Job's response, no further argument, only worship, a declaration of God's greatness.
v3: Job had strayed into things that were solely God's province; there are things about which we can never know enough to satisfy ourselves.
v4-6: Now Job has a first-hand vision of God; he had heard of God, now he met Him. True faith is not second hand. With this vision comes repentance.
God had not promised specific blessing on Job's repentance; we are commanded to repent, irrespective of future blessing. Even so, we are confident that God will bless true repentance. We repent for what we have done, and have failed to do, not because of what we may receive.
v7-9: God accepted Job, for he has spoken what was true, and he has repented at the revelation of God. Although he has spoken truth, he still needed to experience more of God in his life.
In contrast, Job's friends needed his intercession. They have not spoken what was right.
v10-11: Job was restored. Brothers and sisters and acquaintances came to comfort him. The words here indicate that the Lord God was the One who had brought trouble upon Job; He is truly in control of the circumstances of our lives.
v12-17: The details of his restoration, sheep, camels, oxen, donkeys, and seven sons and three daughters. It seems that those killed originally were not raised to life, but more sons and daughters were born to Job.
