“I have not sent them, declares the LORD, but they are prophesying falsely in my name” (27:15). The title of priest or prophet in Israel did not guarantee that someone was telling the truth. While Jeremiah was calling for repentance and warning that God would use Babylon to humble the people, others were prophesying an easy peace (27:9-15). In fact, the people didn’t want to face their own sin and its consequences - Babylonian rule.
“You have broken wooden bars, but you have made in their place bars of iron” (28:13). The “wooden bars” of God’s discipline are for our good, because the alternative is to suffer under the “iron bars” of our own rebellion.
