42:10 turned the captivity. Job had actually been captive under Satan’s control, just as the Lord later allowed Satan to have Peter (Luke 22:31-32), and no doubt others as well. But “through death” Christ has destroyed “him that had the power of death, that is, the devil” (Hebrews 2:14).
42:10 twice as much. Job only acquired the same number of children as before, but his earlier family still belonged to him, safe in the Lord, awaiting a reunion with their new siblings when all later would be together with the Lord.
