Jeremiah 6:10

Jeremiah wondered to whom he could deliver this warning so they could benefit from it. The people he ministered to had closed their ears to his prophecies, and they were so steeped in sin that it was not even possible for them to hear. Messages from the Lord had become offensive to them, and they no longer welcomed them.

"This is the first of more than three dozen times in Jeremiah where the people did not listen to (i.e., they disobeyed) God’s Word." [Note: Dyer, "Jeremiah," p. 1138.]
