'Wall' in the Bible

The wingspan of the cherubim was 20 cubits; the wing of one, five cubits long, touched the wall of the Temple, and its other wing, five cubits long, touched the wing of the other cherub.

The wing of the other cherub, five cubits long, touched the opposite wall of the Temple and its other wing, five cubits long, touched the wing of the first cherub.

King Joash of Israel captured Joash's son King Amaziah of Judah, the grandson of Ahaziah, at Beth-shemesh and brought him back to Jerusalem, where he broke down 400 cubits of the wall of Jerusalem from the Ephraim Gate to the Corner Gate.

Jotham constructed the Upper Gate of the LORD's Temple and did extensive work on the wall of Ophel.

Hezekiah took courage and rebuilt all of the walls that had been broken down. Then he erected watch towers on them, and added another external wall. He fortified the terrace ramparts in the City of David and prepared a large number of weapons and shields.

Later on, Manasseh reinforced the outer wall to the City of David on the west side overlooking the Gihon Valley as far as the Fish Gate. He encircled the Ophel, raising it to a great height.

After this, they set fire to God's Temple, demolished the wall around Jerusalem, burned all of its fortified buildings, and destroyed everything of value.
