'Walls' in the Bible

And he overlaid the house with gold--the beams, the thresholds, the walls, and the doors. And he carved cherubim upon the walls.

He also built Upper Beth-Horon and Lower Beth-Horon, fortified cities [with] walls, gates, and bars;

And he said to Judah, "Let us build these cities and surround [them with] walls, towers, gates, and bars while the land [is] before us, because we have sought Yahweh our God. We have sought and he has given rest to us on every side." So they built and had success.

Then he strengthened himself and built up all the walls that were broken down, and raised towers upon [them] and another wall {outside}. And he strengthened the Millo of the city of David and made much weaponry and small shields.

And they burned the house of God. And they shattered the walls of Jerusalem and burned its citadels with fire and destroyed all the vessels of its treasuries.
