'Castles' in the Bible

And over the king's treasures was Azmaveth the son of Adiel: and over the treasures in the fields, in the cities, and in the villages, and in the castles, was Jonathan the son of Uzziah:

And Jehoshaphat waxed great exceedingly; and he built in Judah castles and cities of store.

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

And wolves shall cry in their castles, and jackals in the pleasant palaces: and her time is near to come, and her days shall not be prolonged.

For Israel hath forgotten his Maker, and builded palaces; and Judah hath multiplied fortified cities: but I will send a fire upon his cities, and it shall devour the castles thereof.
