Joshua 8:18-22

18Then the LORD said to Joshua, “Stretch out the javelin that is in your hand toward Ai, for I will give it into your hand.” And Joshua stretched out the javelin that was in his hand toward the city. 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. 21And when Joshua and all Israel saw that the ambush had captured the city, and that the smoke of the city went up, then they turned back and struck down the men of Ai. 22And the others came out from the city against them, so they were in the midst of Israel, some on this side, and some on that side. And Israel struck them down, until there was left none that survived or escaped.
