Joshua 8:23

²¹And Joshua and all Israel saw that the ambuscade had taken the city, and that the smoke of the city went up to heaven; and they turned and smote the men of Ai.

²²And these came forth out of the city to meet them; and they were in the midst of the army, some being on this side, and some on that; and they smote them until there was not left of them one who survived and escaped.

— Joshua 8:23 —

²⁴And when the children of Israel had ceased slaying all that were in Ai, and in the fields, and in the mountain on the descent, from whence they pursued them even to the end, then Joshua returned to Ai, and smote it with the edge of the sword.

²⁵And they that fell in that day, men and women, were twelve thousand: they slew all the inhabitants of Ai.
