According to St. John Chrysostom, the exiled Jews in Egypt included the section Job 42:18-22, (as found in The Orthodox Study Bible), because they knew they would soon return to Jerusalem, "and desiring this, they could find in the history of Job a significant brazier with which to rekindle their piety"
Job 42:18-22
18It is written that he will rise with those whom the Lord resurrects.
19This man is described in the Syriac book as living in the land of Ausitis, on the borders of Edom and Arabia. Previously his name was Jobab. 20He took an Arabian wife and begot a son named Ennon. But he himself was the Son of his father Zare, one of the sons of Esau, and of his mother, Bosorra. Thus, he was the fifth son from Abraham.
21Now these were the kings who reigned in Edom, over which country he also ruled. First, there was Balak the son of Beor, and the name of his city was Dennaba. But after Balak, there was Jobab, who is called Job. After him, there was Asom, who was ruler out of the country of Teman. After him, there was Adad the son of Barad, who destroyed Midian in the plain of Moab; and the name of his city was Gethaim. 22Now his friends who came to him were: Eliphaz, of the children of Esau, king of the Temanites; Bildad, ruler of the Shuhites; and Zophar, king of the Minians.
