A wall fell upon twenty and seven thousand The wall of the city under which they lay, ready to defend it; or the walls (the singular number being put for the plural, than which nothing is more frequent) of some great castle or fort, in or near the city in which they were now fortifying themselves; or of some part of the city where they lay. This might possibly happen through natural causes; but most probably was effected by the mighty power of God, sending some earthquake, or violent storm, which threw down the walls upon them: and if ever a miracle was to be wrought, now seems to have been the proper season for it; when the blasphemous Syrians denied the sovereign power of God, and thereby in some sort obliged him to give a proof of it; and to show, that he was the God of the plains, as well as of the mountains; and that he could as effectually destroy them in their strongest holds, as in the open fields; and make the very walls, to whose strength they trusted for their defence, to be the instruments of their ruin. But it may be further observed, that it is not said, that all these were killed by the fall of this wall; but only that the wall fell upon them, killing some, and wounding others.
