Did Job's children die because they sinned?

Bildad says, "If your children have sinned against him, he has delivered them into the hand of their disobedience" (8:4). He says if. Set beside it two things the book has already told you. Job offered burnt offerings for them, for he said, "It may be that my sons have sinned, and renounced God in their hearts" (1:5): Job's may be, not a statement that they had. And a messenger told Job how they died: "there came a great wind from the wilderness, and struck the four corners of the house, and it fell on the young men, and they are dead" (1:19). That came after the LORD said to Satan, "Behold, all that he has is in your power" (1:12). The book doesn't say that the children sinned, and it doesn't give their death as a punishment for sin. It says the LORD told Satan, of Job, "you incited me against him, to ruin him without cause" (2:3), and at the end that the friends had "not spoken of me the thing that is right" (42:7). These notes add no reason for the children's death that the book doesn't give.
