Before we listen to what Job says, we must first listen to his silence. He does not curse the robbers or accuse his servants of carelessness. He immediately sees God’s hand in these events. He knows that God is in control of all creation, and therefore the fire and the wind were his fire and wind. Job must have been sitting all the while, because he stands up now and gives expression to his grief by tearing his robe and shaving his head. Even before opening his mouth, he shows his submission to God by falling to the ground. In a literal and figurative sense, he humbles himself under God’s mighty hand
(1 Peter 5:6).
20 Then Job arose and tore his robe and shaved his head and fell on the ground and worshiped.
