'Walls' in the Bible

They destroyed the [walls of the] cities, and each man threw a stone on every piece of good land, covering it [with stones]. And they stopped up all the springs of water and cut down all the good trees, until they left nothing in Kir-hareseth [Moab’s capital city] but its stones. Then the [stone] slingers surrounded the city and destroyed it.

Then the city [wall] was broken into [and conquered]; all the men of war fled by night by way of the gate between the two walls by the king’s garden, though the Chaldeans (Babylonians) were all around the city. And they went by way of the Arabah (the plain of the Jordan).

All the army of the Chaldeans (Babylonians) who were with the captain of the bodyguard tore down the walls around Jerusalem.
