Jeremiah 52:7-8

7Then the city was broken into, and all the soldiers fled. They left the city at night [as Ezekiel prophesied] passing through the gate between the two walls by the king’s garden, though the Chaldeans were all around the city. They fled by way of the Arabah (the Jordan Valley).

8But the army of the Chaldeans pursued the king and overtook Zedekiah in the plains of Jericho; and his entire army was scattered from him.
