'Castles' in the Bible

And Jehoshaphat waxed exceeding great; and he built in Judah castles and store-cities.

And he built cities in the hill-country of Judah, and in the forests he built castles and towers.

And jackals shall cry to one another in their palaces, and wild dogs in the pleasant castles. And her time is near to come, and her days shall not be prolonged.
