Matthew Poole and continuators on Lamentations 3:44

44 Thou hast covered thy self with a cloud, that our prayer should not pass through .

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 onely to apply themselves to God, he had hid his face from them, so as they could get no comfortable fight 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.
