Jeremiah 37:19 - Ellicott's Commentary On The Whole Bible

Where are now your prophets...? — The failure of the past predictions of the false prophets is urged on the king as a reason why he should not trust them in the present crisis. They had assured him (Jeremiah 28:3) that within two years the city should be delivered, and the result had been that it had been besieged. The temporary departure of the Chaldæans had again raised their hopes, and they were now tempting the king with the assurance that the Egyptian army would make short work of them.
