In these chapters the Lord through Jeremiah encourages the people of Judah to accept their punishment and submit themselves to Nebuchadnezzar king of Babylon. It ends up turning into a battle of prophets, as Jeremiah speaks the message from the Lord, and another false prophet says the opposite. The Lord is giving the people a way out if they will just listen to the Lord’s prophet and submit to the Babylonian king. For them, exile is salvation from death and horrible suffering. On the other hand, if they listen to the “positive” prophecy, basically listen to what they want to hear, they will perish.
As throughout the whole OT, the Lord gives his bona fides, why he has the authority to make such judgments:
4 Give them a message for their masters and say, ‘This is what the Lord Almighty, the God of Israel, says: “Tell this to your masters:5 With my great power and outstretched arm I made the earth and its people and the animals that are on it, and I give it to anyone I please.
Hard to argue with that! And he again calls Nebuchadnezzar his servant. The Lord is in charge of this show. And chapter 27 ends with the Lord declaring that even though the furnishings of the house of the Lord have been taken to Babylon, he himself will bring them back and “restore them to this place.” He is always pointing beyond judgment; the payment for sin is not the end of the story, but really only the beginning as we now now.
The false prophet pays for his false prophecies with his life. Jeremiah tells him, “The Lord has not sent you, yet you have persuaded this nation to trust in lies.” Why would someone who knows he’s selling lies, persist in selling with the threat of death hanging over his head. Who knows. Human beings can be irrationally and persistently rebellious. And God is as good as his word. In the seventh month of that year he died.
Maybe he persisted because Jeremiah’s prophecies of submitting to the king of Babylon didn’t seem to make sense. Maybe he preached lies because all the people cheered him on. They may have thought, there is no way God is sending his people into exile. He gave us this land. The Babylonians are heathens. But for whatever reason, they couldn’t discern the word of the Lord over the lies. Those who could, who decided to trust the Lord when it didn’t make sense, escaped with their lives. Those who didn’t perished. This is every human being’s choice: will we trust the Lord.
