Jeremiah 4:21-22

How long [O LORD] must I see the banner [marking the way for flight] And hear the sound of the trumpet [urging the people to run for safety]? “For My people are stupid and foolish,” [says the LORD to Jeremiah]; “They do not know Me; They are foolish children And have no understanding. They are shrewd [enough] to do evil, But they do not know [how] to do good.”
