Joshua 8:14-16

14When the king of Ai saw this, he and all the men of the city hurried out early in the morning to meet Israel in battle at a certain place overlooking the Arabah. But he did not know that an ambush had been set against him behind the city.

15Joshua and all Israel let themselves be driven back before them, and they fled toward the wilderness.

16All the men of Ai were called to pursue them, and they pursued Joshua and were lured away from the city.
