Isaiah 2:15

and on every high tower, and on every fortified wall;

And the fortress of the high fort of your walls He will lay low, bring to the ground, to the dust.

Treasury of Scripture Knowledge

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

I will make waste mountains and hills, and dry up all their plants. And I will make the rivers coastlands, and I will dry up the pools.

And a bastard shall dwell in Ashdod, and I will cut off the pride of the Philistines.

And every island fled away, and mountains were not found.
