Isaiah 2:15

against every high tower, and against every fortified wall;

And the high fortifications of his walls he will bring down, lay low, and cast to the ground, to the dust.

Treasury of Scripture Knowledge

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

I will lay waste mountains and hills, and dry up all their vegetation; I will turn the rivers into islands, and dry up the pools.

a mixed people shall dwell in Ashdod, and I will cut off the pride of Philistia.

And every island fled away, and no mountains were to be found.
