Isaiah 2:15

Against every high tower,
Against every fortified wall,

The high fortifications of your 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 the mountains and hills
And wither all their vegetation;
I will turn the rivers into coastlands
And dry up the ponds.

And a mongrel race will live in Ashdod,
And I will put an end to the pride and arrogance of the Philistines.

Then every island fled away, and no mountains could be found.
