Satan, the accuser of the brethren, had challenged God to destroy Job "without cause" (2:4). Satan, unknowingly to Job, had been defeated by Job's blessing the Lord rather than cursing Him (1:21;2:10). Now, Satan's challenge was that Job would curse God if Job's own physical life was tormented. There are other instances in the Bible where God allowed Satan certain liberties with His servants. Peter would have been sifted like wheat if Jesus allowed it (Luke 22:31). Paul had a "messenger of Satan" buffet him (II Corinthians 12:7). Hymenaeus and Alexander were delivered to Satan "that they may learn not to blaspheme" (I Timothy 1:20). However, Satan can do no more than God allows. In this sense, Satan is just a tool in God's ultimate will. Job's three friends wept when they saw Job's physical condition. They silently supported him with their presence for seven days. Finally, Job unleashes his feelings in an emotional rant. This sets in motion a series of dialogues, set in poetry, which examine the depths of human suffering.
