Charles Ellicott Commentary Jeremiah 21:10

"For I have set my face upon this city for evil, and not for good, saith Jehovah: it shall be given into the hand of the king of Babylon, and he shall burn it with fire." — Jeremiah 21:10 (ASV)

He shall burn it with fire. —Another detail of prediction fulfilled literally in Jeremiah 52:13. Such a destruction was, of course, common enough as an incident of the capture of besieged cities, but it was not universal. Often, indeed, the conquerors sought to preserve the city and to occupy its palaces. The actual answer to Zedekiah’s messengers possibly ended with this verse.
