Joshua 8:16

12He took about five thousand men, and set them in ambush between Bethel and Ai, on the west side of the city.

13So they set the people, even all the army who was on the north of the city, and their ambush on the west of the city; and Joshua went that night into the middle of the valley.

14When the king of Ai saw it, they hurried and rose up early, and the men of the city went out against Israel to battle, he and all his people, at the time appointed, before the Arabah; but he didn’t know that there was an ambush against him behind the city.

15Joshua and all Israel made as if they were beaten before them, and fled by the way of the wilderness.

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

17There was not a man left in Ai or Bethel who didn’t go out after Israel. They left the city open, and pursued Israel.

18The LORD 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.

19The 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. They hurried and set the city on fire.

20When 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. The people who fled to the wilderness turned back on the pursuers.
