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.
