Jeremiah 52:6-7

6By 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.

7Then 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.
