Joshua 8:19-20

19And the men in the ambush rose quickly out of their place, and as soon as he had stretched out his hand, they ran and entered the city and captured it. And they hurried to set the city on fire. 20So when the men of Ai looked back, behold, the smoke of the city went up to heaven, and they had no power to flee this way or that, for the people who fled to the wilderness turned back against the pursuers.
