'Fort' in the Bible

Surely the palace hath been left, The multitude of the city forsaken, Fort and watch-tower hath been for dens unto the age, A joy of wild asses -- a pasture of herds;

Thy daughters in the field by sword he slayeth, And he hath made against thee a fort, And hath poured out against thee a mount, And hath raised against thee a buckler.

And thou, O tower of Eder, Fort of the daughter of Zion, unto thee it cometh, Yea, come in hath the former rule, The kingdom to the daughter of Jerusalem.
