Matthew Henry on Job 1:13-19

Satan brought Job's troubles upon him on the day that his children began their course of feasting. The troubles all came upon Job at once; while one messenger of evil tidings was speaking, another followed. His dearest and most valuable possessions were his ten children; news is brought him that they are killed. They were taken away when he had most need of them to comfort him under other losses. In God only have we a help present at all times. (Job 1:20-22)
