His horses will be so many that they will cover you with dust. Your walls will tremble at the noise of the warhorses, wagons and chariots when he enters your gates as men enter a city whose walls have been broken through.
NIV
Because of the great number of [Nebuchadrezzar's] horses, their dust will cover you; your walls [O Tyre] will shake at the noise of the horsemen and of the wagon wheels and of the chariots, when he enters into your gates as men enter into the city in whose walls there has been made a breach.
AMP
By reason of the abundance of his horses their dust shall cover thee: thy walls shall shake at the noise of the horsemen, and of the wheels, and of the chariots, when he shall enter into thy gates, as men enter into a city wherein is made a breach.
