Joshua 8:14-16

14So it came to pass when the king of Ai saw this, the men of the city hurried and rose up early, and went out to meet Israel in battle, he and all his people at the appointed place facing the Arabah. But he did not know that there was an ambush against him behind the city.

15So Joshua and all Israel pretended to be beaten before them and fled by the way of the wilderness.

16Then all the people who were in Ai were summoned to pursue them, so they pursued Joshua and were drawn away from the city.
