Joshua 8:13-23

13 So they stationed the forces, the main encampment that was north of the city and its rear guard west of the city. But Joshua spent that night in the valley.
14 When the king of Ai saw this, he and all his people, the inhabitants of the city, hurried out early in the morning to the meeting place facing the Arabah to meet Israel in battle; but he did not know that there was an ambush against him behind the city.
15 And Joshua and all Israel made a pretense of being beaten before them, and fled in the direction of the wilderness.
16 So all the people who were in the city were called together to pursue them, and as they pursued Joshua they were drawn away from the city.
17 There was not a man left in Ai or Bethel who did not go out after Israel; they left the city open, and pursued Israel.
18 Then the Lord said to Joshua, "Stretch out the sword that is in your hand toward Ai; for I will give it into your hand." And Joshua stretched out the sword that was in his hand toward the city.
19 As soon as he stretched out his hand, the troops in ambush rose quickly out of their place and rushed forward. They entered the city, took it, and at once set the city on fire.
20 So when the men of Ai looked back, the smoke of the city was rising to the sky. They had no power to flee this way or that, for the people who fled to the wilderness turned back against the pursuers.
21 When Joshua and all Israel saw that the ambush had taken the city and that the smoke of the city was rising, then they turned back and struck down the men of Ai.
22 And the others came out from the city against them; so they were surrounded by Israelites, some on one side, and some on the other; and Israel struck them down until no one was left who survived or escaped.
23 But the king of Ai was taken alive and brought to Joshua.
