John Wesley on Job 1:19

The young men - This was the greatest of Job's losses, and therefore Satan reserved it to the last, that if the other provocations failed, this might make him curse God. They died by a wind of the devils raising, but which seemed to be the immediate hand of God. And they were taken away, when he had the most need of them, to comfort him under all his other losses. Such miserable comforters are creatures: in God we have a constant and sufficient help.
