God had covered them with wrath, overwhelming them with afflictions. so as they had no way to escape; and whereas in this distress they had nothing else to do but only to apply themselves to God, he had hid his face from them, so as they could get no comfortable sight of him; he was as one covered with a cloud, that could not be discerned through that opacous body. What is meant by this cloud, whether his fixed resolution to punish them, or his fresh remembrance of their sins, or his just will to be revenged on them, seems too curiously inquired. The phrase is a metaphor, and signifies no more than that God would not hear their prayers in their distress.
