The description of the siege is that of a town invested by land.
Nebuchadrezzar - Jeremiah 21:2 note.
Lift up the buckler - i. e., set a wall of shields, under cover of which the walls could be approached.
Engines of war - Or, his battering ram. “axes” swords. They who would break flown the towers, rush on with their swords to slay the defenders.
Garrisons - pillars, on which stood statues of some protecting god. Compare 2 Kings 10:26.
The siege had been on land, but the victory was to be completed by the subjection of the island-citadel.
