Job 42:8-10

8And now, take for yourselves seven bullocks and seven rams, and go to my servant Job, and offer up for yourselves a burnt-offering; and my servant Job shall pray for you, for him will I accept: lest I deal with you [after your] folly, for ye have not spoken of me rightly, like my servant Job.

9Then Eliphaz the Temanite, and Bildad the Shuhite, and Zophar the Naamathite, went and did according as Jehovah had said unto them; and Jehovah accepted Job.

10And Jehovah turned the captivity of Job, when he had prayed for his friends; and Jehovah gave Job twice as much as he had before.
