Jeremiah 39:4

When Zedekiah saw the invaders within the city, he and many of the Judean soldiers tried to escape by night, exiting Jerusalem by a gate in the king’s garden. This was perhaps the Fountain Gate near the Pool of Siloam (cf. Nehemiah 2:14; Nehemiah 3:15; Nehemiah 12:37) or the Horse Gate (cf. Nehemiah 3:28). [Note: Keil, 2:121, argued for the Horse Gate.] They took a passageway between the two walls of the city there (cf. Isaiah 22:11) and headed east toward the Arabah (Jordan Valley). Zedekiah evidently wanted to escape to Ammon, an ally of Judah at this time (cf. Ezekiel 21:18-23).
