Here the Lord compels them to look back, and trace the causes or all their past calamity. The idolatry of themselves, and their fathers, had already brought upon them, and their land, the awful judgments which had prompted them to flee into Egypt.
Jeremiah 44:20-23
20 Then Jeremiah said unto all the people, to the men, and to the women, and to all the people which had given him that answer, saying,
21 The incense that ye burned in the cities of Judah, and in the streets of Jerusalem, ye, and your fathers, your kings, and your princes, and the people of the land, did not the LORD remember them, and came it not into his mind?
22 So that the LORD could no longer bear, because of the evil of your doings, and because of the abominations which ye have committed; therefore is your land a desolation, and an astonishment, and a curse, without an inhabitant, as at this day.
23 Because ye have burned incense, and because ye have sinned against the LORD, and have not obeyed the voice of the LORD, nor walked in his law, nor in his statutes, nor in his testimonies; therefore this evil is happened unto you, as at this day.
