'Citadel' in the Bible

Arise, and let us attack by night, and let us destroy her citadel fortresses."

Thus says Yahweh: 'Look, I [will] restore the fortunes of the tents of Jacob, and I will have compassion on his dwellings, and [the] city will be rebuilt upon its mound, and [the] citadel fortress will stand on its rightful site.

"And I will kindle a fire at the wall of Damascus, and it will devour the citadel fortresses of Ben-hadad."
