Thou shalt be built no more - If this refer to Nebuchadnezzar's capture of the city, old Tyre must be intended: that was destroyed by him, and never rebuilt. But I doubt whether the whole of this prophecy do not refer to the taking of Tyre by Alexander, three hundred years after its capture by Nebuchadnezzar. Indeed it may include more recent conquests of this important city. It went through a variety of vicissitudes till 1289, when it and the neighboring towns were sacked and ravaged by the Mamelukes. Mr. Maundrell, who visited this place, says, "it is a Babel of broken walls, pillars, vaults, etc., there being not so much as one entire house left! Its present inhabitants are only a few poor wretches, harbouring themselves in the vaults, and subsisting chiefly on fishing; who seem to be preserved in this place by Divine Providence as a visible argument how God has fulfilled his word concerning Tyre, that it should be the top of a rock, a place for fishers to dry their nets on."
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.
