Jeremiah 6:18

Therefore hear, ye nations, and know, O congregation, what is among them.

The nations and the whole congregation are summoned to hear and to recognize the rebellion and wrongdoing found among God's people. They stand as witnesses to a refusal to listen to the watchmen, to accept correction, and to obey God's words and law. The evil that comes upon the disobedient is the fruit of their own thoughts. This call to hear is to be taken to heart in resisting sin and in studying and practicing God's word.
