'Wall' in the Bible

Now look, I have made you {today} as a fortified city and as an iron pillar and a bronze wall against all the land, against the kings of Judah, against its princes, against its priests, and against the people of the land.

And I will make you to this people a wall of fortified bronze, and they will fight against you, but they will not prevail over you, for I [am] with you, to save you, and to deliver you," {declares} Yahweh.

'Thus says Yahweh, the God of Israel: "Look, I [am] about to turn back the weapons of war that [are] in your hands, [with] which you [are] fighting against them, the king of Babylon and the Chaldeans who are laying siege to you from outside the wall, and I will gather them into the center of this city.

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

And I will punish Bel in Babylon, and I will wrench out from his mouth {what he has swallowed}. And [the] nations will not stream towards him [any] longer {what's worse}, the wall of Babylon has fallen.
