Job 42:10 (ESV)

10 And the LORD restored the fortunes of Job, when he had prayed for his friends. And the LORD gave Job twice as much as he had before.

God’s victory over Satan is decisive. By now, it has become impossible for Satan to argue that Job has not yet been tested far enough (Job 2:4). Moreover, Job has humbled himself and repented of his arrogance. There is no more reason to prolong Job’s suffering. From justifying Job, God proceeds to exalting him.

It is at the highest point of Job’s obedience—his prayer for his enemies—that his own situation also begins to change. His health is probably the first blessing to return. Then his possessions gradually become twice as much as before.

In God’s restoration of Job’s wealth, it is possible to see a foreshadowing of the law given in Exodus 22:1–9. Here it is said that a thief should give back double the amount that he had stolen. Satan had taken everything from Job. Now God ensures that Job is doubly repaid.
