Joshua 8:14-16

14And it came to pass when the king of Ai saw it, that the men of the city hasted and rose early, and went out against Israel to battle, he and all his people, at the appointed place before the plain. But he knew not that there was an ambush against him behind the city.

15And Joshua and all Israel let themselves be beaten before them; and they fled by the way of the wilderness.

16And all the people that were in the city were called together to pursue after them; and they pursued after Joshua, and were drawn away from the city.
