Isaiah 2:15

And on every high tower, and on every strong wall;

And the strong tower of your walls has been broken by him, made low, and crushed even to the dust.

Treasury of Scripture Knowledge

And upon every high tower, and upon every fenced wall,

I will make waste mountains and hills, drying up all their plants; and I will make rivers dry, and pools dry land.

And a mixed people will be living in Ashdod, and I will have the pride of the Philistines cut off.

And every island went in flight, and the mountains were seen no longer.
