In his desire to protect God’s righteousness, Bildad comes with this sharp accusation: Job’s ten children had died because of their own sin. What a painful accusation this must have been to a father who had always taken care that his children would not stray from God’s ways (Job 1:5).
Of course, Bildad cannot point out the way in which Job’s children had sinned. Still he forces the complex matter of human suffering into a neat, simple scheme: all suffering is punishment from God.
4 If your children have sinned against him, he has delivered them into the hand of their transgression.
