Job had everything. He was a man of God, had many children, livestock, etc. He was blameless. Satan made a bet to God that if he is blameless, then why does he have everything. If everything was taken from him, surely he would curse God. But God proved Satan wrong. Even when everything was taken from him, and friends betraying him, and elders telling him he must've done something wrong for this to happen, Job never cursed God, and Elihu, a young man, comforted Job and proved the elders wrong. God then gave everything that was taken from him back, Proof that even the Blameless, despite having everyone against him, elders trying to point out, and all that he had was stolen, is still Blameless.
