'Fortified City' in the Bible

“The fortified city will disappear from Ephraim,And sovereignty from DamascusAnd the remnant of Aram;They will be like the glory of the sons of Israel,”Declares the Lord of hosts.

For You have made a city into a heap,A fortified city into a ruin;A palace of strangers is a city no more,It will never be rebuilt.

For the fortified city is isolated,A homestead forlorn and forsaken like the desert;There the calf will graze,And there it will lie down and feed on its branches.
