Joshua 8:23-29

23Only the king of Ai was taken alive and brought to Joshua.

24When the Israelite army finished chasing and killing all the men of Ai in the open fields, they went back and finished off everyone inside.

25So the entire population of Ai, including men and women, was wiped out that day—12,000 in all.

26For Joshua kept holding out his spear until everyone who had lived in Ai was completely destroyed.

27Only the livestock and the treasures of the town were not destroyed, for the Israelites kept these as plunder for themselves, as the Lord had commanded Joshua.

28So Joshua burned the town of Ai, and it became a permanent mound of ruins, desolate to this very day.

29Joshua impaled the king of Ai on a sharpened pole and left him there until evening. At sunset the Israelites took down the body, as Joshua commanded, and threw it in front of the town gate. They piled a great heap of stones over him that can still be seen today.
