Joshua 8:24-26

24The Israelites killed all the men who had lived in Ai. They killed them when they chased them towards the desert. Then the Israelite soldiers went back to Ai and they killed everyone there.

25All the people of Ai died on that day. That was 12,000 men and women.

26Joshua continued to point his spear at Ai, until his army had killed every person who lived there.
