Joshua 8:20-24

20And the men of Ai turned and saw, and behold, the smoke of the city went up to heaven, and they had no power to flee this way or that way; and the people that fled to the wilderness turned upon the pursuers.

21When Joshua and all Israel saw that the ambush had taken the city, and that the smoke of the city went up, they turned again, and slew the men of Ai.

22And the others went out of the city against them; so they were in the midst of Israel, some on this side, and some on that side; and they smote them, until they let none of them escape or flee away.

23And the king of Ai they took alive, and brought him to Joshua.

24And it came to pass when Israel had ended slaying all the inhabitants of Ai in the field, in the wilderness wherein they had chased them, and they had all fallen by the edge of the sword, until they were consumed, that all Israel returned to Ai, and smote it with the edge of the sword.
