'Stronghold' in the Bible

And I, in the first year of Darius the Mede, my standing is for a strengthener, and for a stronghold to him;

And one hath stood up from a branch of her roots, in his station, and he cometh in unto the bulwark, yea, he cometh into a stronghold of the king of the south, and hath wrought against them, and hath done mightily;

and his sons stir themselves up, and have gathered a multitude of great forces, and he hath certainly come in, and overflowed, and passed through, and he turneth back, and they stir themselves up unto his stronghold.

And strong ones out of him stand up, and have polluted the sanctuary, the stronghold, and have turned aside the continual sacrifice, and appointed the desolating abomination.
