The prophet turns to the Ninevites and their preparations for defence. He shall recount his worthies; he remembers his nobles. The King of Nineveh calls to mind the mighty captains who have often led his armies to victory, and sends them to defend the walls (comp.
Nahum 3:18). The LXX; anticipating the next clause, adds here, καὶ φεύξονται ἡμέρας, "and they shall flee by day." They shall stumble in their walk. In their fear and baste, or half drunken, they totter and stumble as they hasten to the walls of the city.
The defence shall be prepared; literally, the covering is prepared. If this refers to the operations of the Ninevites, it means some kind of breastwork or fascine erected between the towers; but it most probably depicts the sight that meets their eyes from the wails.
They see the besiegers bringing up their mantelets and towers. As used by the Assyrians, the machine called "the covering" is either a wooden tower or a wicker mantelet in which was suspended a battering ram.
It stood on four or six wheels, and the larger sort had archers posted in the various stories, both to annoy the enemy and to defend the engine. The rams were provided with lance headed extremities, and must have rather picked at and loosened the courses of bricks of which the walls were composed than battered them down.
The Septuagint rendering applies rather to the besieged, ἐτοιμάσουσι τὰς προφυλακὰς αὐτῶν, "They shall prepare their defences."
