The Babylonian Conquest

Jeremiah 39:1–2 NKJV

In the ninth year of Zedekiah king of Judah, in the tenth month, Nebuchadnezzar king of Babylon and all his army came against Jerusalem, and besieged it. In the eleventh year of Zedekiah, in the fourth month, on the ninth day of the month, the city was penetrated.

Jeremiah 52:4–7 NKJV

Now it came to pass in the ninth year of his reign, in the tenth month, on the tenth day of the month, that Nebuchadnezzar king of Babylon and all his army came against Jerusalem and encamped against it; and they built a siege wall against it all around. So the city was besieged until the eleventh year of King Zedekiah. By the fourth month, on the ninth day of the month, the famine had become so severe in the city that there was no food for the people of the land. Then the city wall was broken through, and all the men of war fled and went out of the city at night by way of the gate between the two walls, which was by the king’s garden, even though the Chaldeans were near the city all around. And they went by way of the plain.
