Verse 21. - Remember them; i.e. the repeated acts of idolatry.

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.That incense that ye burnt in the cities of Judah, and in the streets of Jerusalem,.... To false gods, to the queen of heaven, to the host thereof:

ye, and your fathers, your kings, and your princes, and the people of the land; on which account they pleaded antiquity, authority, and the general consent of the people, as on their side, which the prophet allows; but it all signified nothing:

did not the Lord remember them, and came it not into his mind? either the incense they offered up to strange gods, or the persons that did it? did he take no notice of these idolatrous practices, and of these idolaters? he did; he laid up these things in his mind; he showed a proper resentment of them, and in due time punished for them.
