Jeremiah 52:6-7

6By July 18 in the eleventh year of Zedekiah’s reign, the famine in the city had become very severe, and the last of the food was entirely gone.

7Then a section of the city wall was broken down, and all the soldiers fled. Since the city was surrounded by the Babylonians, they waited for nightfall. Then they slipped through the gate between the two walls behind the king’s garden and headed toward the Jordan Valley.
