Wait a second isn't there a story that can help us come to a conclusion regarding Yermiyhu
Micha the prophet
Jerusalem will be destroyed and the har habayit will be scattered as well and desolate.
Rather then killing him, let's listen and change because he was sent from God
Kohanim and Naviim
Really we should be comparing this case to a different story, the story of Uriyahu.
The Elders gathered during this trial and confirmed their groups' opinion. They realized that they knew a story that was applicable to the situation at hand... the story of Micha
Stop doing idol worship, return to God or Jerusalem will be destroyed
we should kill him
The story of Micha: Micha gave a prophecy to all of Yehuda saying that Jerusalem will be destroyed and the har habayit will be scattered as well and desolate. The people didn't kill Micha because they feared Hashem. B"Y turned back to good ways and Jerusalem did not become a field.
I will bring him back to the king to have him killed
The Kohanim and Naviim were discussing their view on this trial and consolidated their groups' opinion. They decided to bring forward a story to compare the situation to.
Don't worry I'll save you, Yirmiyahu
Uriyahu prophesied in Hashem’s name saying that the land and the people will be destroyed, the people heard his words and wanted to kill him.
People of Yehuda
When Uriyahu fled to mitzrayim, the king sent people after him. They brought uriyahu to the king and murdered him.
Men sent from the king
Meanwhile, Achikam, the son of Shafan, is here to save Yirmiyahu from being killed.
