Albert Barnes Commentary Jeremiah 32:24

"Behold, the mounds, they are come unto the city to take it; and the city is given into the hand of the Chaldeans that fight against it, because of the sword, and of the famine, and of the pestilence; and what thou hast spoken is come to pass; and, behold, thou seest it." — Jeremiah 32:24 (ASV)
