Joshua 8:18 WEB

¹⁶  All the people who were in the city were called together to pursue after them: and they pursued after Joshua, and were drawn away from the city.

¹⁷  There was not a man left in Ai or Beth El, who didn't go out after Israel: and they left the city open, and pursued after Israel.

¹⁸  Yahweh said to Joshua, Stretch out the javelin that is in your hand toward Ai; for I will give it into your hand. Joshua stretched out the javelin that was in his hand toward the city.

¹⁹  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 hurried and set the city on fire.

²⁰  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 who fled to the wilderness turned back on the pursuers.
