Ezekiel 26:8,9

“He will slay with the sword your daughters in the surrounding countryside, and he will make forts against you, and cast up a mount against you, and raise up the buckler (large body shield) against you, and he will set his battering-engines against your walls, and with his axes he will break down your towers.”

All the devices of ancient warfare would be applied against Tyre. The villages around would be laid waste. Siege forts/walls would be built and a mount to make the defenders more accessible. Walls of shields would be utilised in the assaults, and battering-rams would be brought against the walls. Axes would be applied to the wooden defence towers. All this against the mainland town for the island could not be reached.

There is a deliberate attempt here to demonstrate that Tyre, with all her pride and claims, is really inferior compared to this supreme king who is Yahweh's instrument.
