Jeremiah 39:4

And it came to pass that, when Zedekiah, the king of Judah, saw them, and all the men of war, that is, when Zedekiah and his soldiers noted the pomp and the warlike appearance of the Chaldean generals at close range, then they fled and went forth out of the city, the upper city, where the royal palace was situated, by night, by the way of the king's garden, by the gate betwixt the two walls, those on the western edge of Ophel and on the eastern edge of Zion, for the royal gardens were situated southeast of the city, on the slopes of the Kidron Valley; and he went out the way of the plain, the meadows of the Jordan near Jericho. There may have been a gap in the lines of the besieging army at this point, since the upper city was almost impregnable from the east and southeast; so this plan was the only one which promised success.
