Joshua 8:19-20

¹⁹And the ambush arose quickly out of their place, and they ran as soon as he had stretched out his hand, and entered into the city, and took it; and they hasted and set the city on fire. ²⁰And when the men of Ai looked behind them, they saw, and, behold, the smoke of the city ascended up to heaven, and they had no power to flee this way or that way: and the people that fled to the wilderness turned back upon the pursuers.
