'Fortresses' in the Bible

For Israel has forgotten his Maker and built palaces; and Judah has multiplied fortified cities; but I will send a fire on his cities, and it will devour its fortresses."

Therefore a battle roar will arise among your people, and all your fortresses will be destroyed, as Shalman destroyed Beth Arbel in the day of battle. The mother was dashed in pieces with her children.
