A wall fell upon twenty and seven thousand - From the first view of this text it would appear that when the Syrians fled to Aphek, and shut themselves within the walls, the Israelites immediately brought all hands, and sapped the walls, in consequence of which a large portion fell, and buried twenty-seven thousand men. But perhaps the hand of God was more immediately in this disaster; probably a burning wind is meant. See at the end of the chapter, 1 Kings 20:43; (note).
Came into the city, into an inner chamber - However the passage above may be understood, the city was now, in effect, taken; and Ben-hadad either betook himself with his few followers to the citadel or to some secret hiding-place, where he held the council with his servants immediately mentioned.
A wall - “The wall,” i. e., the wall of the town. We may suppose a terrific earthquake during the siege of the place, while the Syrians were manning the defenses in full force, which threw down the wall where they were most thickly crowded upon it, and buried them in its ruins. Ben-hadad fled from the wall, where he had been at the time of the disaster, into the inner parts of the city - probably to some massive stronghold - and there concealed himself.
