'Fortress' in the Bible

But out of a shoot from her roots shall one stand up in his place, who shall come unto the army, and shall enter into the fortress of the king of the north, and shall deal against them, and shall prevail.

And his sons shall war, and shall assemble a multitude of great forces, which shall come on, and overflow, and pass through; and they shall return and war, even to his fortress.

And forces shall stand on his part, and they shall profane the sanctuary, even the fortress, and shall take away the continual burnt-offering , and they shall set up the abomination that maketh desolate.
