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 have committed in the land of Judah, and in the streets of Jerusalem?
Jeremiah 44:9 belongs to the part of the book covering the history of the two years before Jerusalem fell. It belongs to the closing chapters, which include the prophet's personal experiences and his journey into Egypt. It recalls the idolatry practiced by the ancestors, the kings of Judah, their wives, and the people and their wives in the land of Judah and in the streets of Jerusalem.
In the surrounding account, this wickedness includes worship of the queen of heaven by burning incense, pouring out drink offerings, and making cakes for her. In that account the people say they learned these practices and continued them across generations. The cakes for the queen of heaven are an unbloody offering. Together with the next verse, the verse shows that the people had committed wickedness and had not obeyed God's voice or kept His covenant, so they were not entitled in their own persons to the covenant's promised blessings.
