2 Kings 25:2-4

The city came under siege [for nearly two years] until the eleventh year of King Zedekiah. On the ninth day of the fourth month the famine [caused by the siege] was severe in the city; there was no food for the people of the land. 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).
