Joshua 8:20-24

20Now the men of Ai looked back and saw, behold, the smoke of the city rising up to the sky! They had no place to flee this way or that, since the people who had been fleeing to the wilderness turned back upon the pursuers.

21When Joshua and all Israel saw that the ambush had captured the city and that the smoke of the city rose up, they turned back and struck down the men of Ai.

22The others also came out of the city against them, so they were surrounded by Israel, some on this side and some on that side. They struck them down until not one survivor or fugitive was left.

23But they captured the king of Ai alive and brought him to Joshua.

24After Israel had finished killing all the inhabitants of Ai in the field in the wilderness where they pursued them, and all of them were fallen by the edge of the sword until they were consumed, all Israel returned to Ai and struck it with the edge of the sword.
