'Fortresses' in the Bible

So Jehoshaphat became greater and greater. He built fortresses and storage cities in Judah.

He has stretched out His hand over the sea,He has shaken the kingdoms;The Lord has given a command concerning Canaan to destroy her strongholds and her fortresses [like Tyre and Sidon].

He will dwell on the heights,His place of defense will be the fortress of rocks,His bread will be given him;His water will be permanent.

Thorns will come up in its fortified palaces,Nettles and brambles in its fortified cities;It will be a haunt for jackals,An abode for ostriches.

Then he will turn back toward the fortresses of his own land [of Syria], but he will stumble and fall and not be found.

Instead, he will honor a god of fortresses, a god whom his fathers did not know; he will honor him with gold and silver, with precious stones and with expensive things.

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

Therefore an uproar will arise among your people,And all your fortresses will be destroyed,As Shalman destroyed Beth-arbel on the day of battle,When mothers were dashed in pieces with their children.

All your fortresses are [nothing but] fig trees with ripe figs—When shaken they fall into the mouth of the eater.

Draw water for a [long, continued] siege!Strengthen your fortresses!Go down to the clay pits, trample the mortar!Prepare the brick kiln [to burn bricks for the rampart]!
