Charles Ellicott Commentary Jeremiah 37:9-10

"Thus saith Jehovah, Deceive not yourselves, saying, The Chaldeans shall surely depart from us; for they shall not depart. For though ye had smitten the whole army of the Chaldeans that fight against you, and there remained but wounded men among them, yea would they rise up every man in his tent, and burn this city with fire." — Jeremiah 37:9-10 (ASV)

Deceive not yourselves ... —Literally, Deceive not your souls. The words indicate that the king and his counselors had buoyed themselves up with expectations of deliverance. The chariots and horses of Egypt were, they thought, certain to defeat the Chaldeans in a pitched battle. The prophet tells them, in the language of a bold hyperbole, reminding us of Isaiah 30:17, that even the wounded remnant of the Chaldean army would be strong enough to accomplish the purpose of Jehovah in the destruction of Jerusalem.
