Charles Ellicott Commentary Jeremiah 44:9

"Have ye forgotten the wickedness of your fathers, and the wickedness of the kings of Judah, and the wickedness of their wives, and your own wickedness, and the wickedness of your wives which they committed in the land of Judah, and in the streets of Jerusalem?" — Jeremiah 44:9 (ASV)

The wickedness of their wives. —Similar to the first introduction of idolatry under Solomon (1 Kings 11:4), this pattern was also seen in the reigns of his successors. For example, in the case of Asa (1 Kings 15:13) and Ahaziah (2 Chronicles 22:2), the queens at that time, often of foreign birth, seem to have been the chief patrons of foreign and idolatrous worship. Their example was naturally followed by the wives of the nobles and other citizens.
