Isaiah 25:12

And the fortress of the high fort of thy walls... — Primarily the words, as interpreted by Isaiah 25:10, point to Kir-Moab (Isaiah 15:1) as the stronghold of the nation. Beyond this they predict a like destruction of every stronghold, every rock-built fortress (2 Corinthians 10:5) of the great world-power of which Moab was for the time the symbol.
