Job 42:8-10

8Now therefore take seven bulls and seven rams and go to my servant Job and offer up a burnt offering for yourselves. And my servant Job shall pray for you, for I will accept his prayer not to deal with you according to your folly. For you have not spoken of me what is right, as my servant Job has."

9So Eliphaz the Temanite and Bildad the Shuhite and Zophar the Naamathite went and did what the Lord had told them, and the Lord accepted Job's prayer.

10And 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.
