Scholars see this verse as a sharp, urgent shift in Jeremiah's message. After a long section on idolatry, he returns to the main theme: judgment is no longer a future threat, but an immediate reality. Commentators like Calvin note the tone is almost ironic, like a messenger shouting war news to a complacent people. The command to 'pack up' signifies that the time for repentance has passed and exile is at the door.
