'Strongholds' in the Bible

Hyenas will howl in its strongholds, and jackals will make their dens in its citadels. Its time is close at hand, and its days will not be extended any further.

He has stretched out his hand over the sea; he has made kingdoms tremble. The LORD has issued orders concerning Canaan to destroy its strongholds.

He high places doth inhabit, Strongholds of rock are his high tower, His bread hath been given, his waters stedfast.

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.
