Matthew Henry on Jeremiah 44:20-30

Whatever evil comes upon us, it is because we have sinned against the Lord; we should therefore stand in awe, and sin not. Since they were determined to persist in their idolatry, God would go on to punish them. What little remains of religion were among them, would be lost. The creature-comforts and confidences from which we promise ourselves most, may fail as soon as those from which we promise ourselves least; and all are what God makes them, not what we fancy them to be. Well-grounded hopes of our having a part in the Divine mercy, are always united with repentance and obedience.
