Albert Barnes Commentary Jeremiah 37:7-10

"Thus saith Jehovah, the God of Israel, Thus shall ye say to the king of Judah, that sent you unto me to inquire of me: Behold, Pharaoh`s army, which is come forth to help you, shall return to Egypt into their own land. And the Chaldeans shall come again, and fight against this city; and they shall take it, and burn it with fire. 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 37:7-10 (ASV)

Jeremiah’s answer here is even more unfavorable than that which is given in (Jeremiah 21:4–7). So hopeless is resistance that the disabled men among the Chaldeans would alone suffice to capture the city and burn it to the ground.
