'Fortresses' in the Bible

Hyenas will howl in the fortresses,and jackals, in the luxurious palaces.Babylon’s time is almost up;her days are almost over.

He stretched out His hand over the sea;He made kingdoms tremble.The Lord has commandedthat the Canaanite fortresses be destroyed.

"Look at the land of the Chaldeans! This is a people that no longer exist; Assyria destined her for desert creatures. They raised up her siege towers, they stripped her fortresses bare and turned her into a ruin.

he will dwell on the heights;his refuge will be the rocky fortresses,his food provided, his water assured.

And thorns shall come up in her palaces, nettles and brambles in the fortresses thereof: and it shall be an habitation of dragons, and a court for owls.
