'Stronghold' in the Bible

Wail, you ships of Tarshish, because your stronghold is destroyed!"

For you have been a stronghold for the poor, a stronghold for the needy in distress, a shelter from the storm and a shade from the heat for the blistering attack from the ruthless is like a rainstorm beating against a wall,

Their stronghold will vanish by reason of terror, and their commanders will be filled with alarm because of the battle standard," declares the LORD, whose fire is in Zion and whose furnace is in Jerusalem.
