Job never prays for his own restoration or prosperity. He desires only to know the mind, heart, and ways of God in the midst of his suffering. When he does encounter God in face to face meeting, he turns, repents, and humbles himself. Then, he prays for the friends who have misjudged him in their own ignorance.

"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."

(Job 42:10 ESV)
