“The prophet Jeremiah
All the people of Judah,
All the inhabitants of Jerusalem.”
It is not clear how Jeremiah the prophet was able to speak to all the people of Judah and Jerusalem together. This would assume that they were all in one place. We just had a specific time, but it is hard to find a place big enough for this kind of an assembly. Obviously it is a euphemism to indicate that Jeremiah’s words should be heard by all the people of Judah and Jerusalem.
