'Fortresses' in the Bible

So he will turn his face toward the fortresses of his own land, but he will stumble and fall and be found no more.

But instead he will honor a god of fortresses, a god whom his fathers did not know; he will honor him with gold, silver, costly stones and treasures.

He will take action against the strongest of fortresses with the help of a foreign god; he will give great honor to those who acknowledge him and will cause them to rule over the many, and will parcel out land for a price.
