'Walls' in the Bible

He overlaid also the house, the beams, the thresholds, and its walls, and its doors, with gold; and engraved cherubim on the walls.

Also he built Beth Horon the upper, and Beth Horon the lower, fortified cities, with walls, gates, and bars;

For he said to Judah, "Let us build these cities, and make walls around them, with towers, gates, and bars. The land is yet before us, because we have sought Yahweh our God; we have sought him, and he has given us rest on every side." So they built and prospered.
