Joshua 8:27

25All that fell that day, both of men and women, were twelve thousand, even all the people of Ai.

26For Joshua didn’t draw back his hand, with which he stretched out the javelin, until he had utterly destroyed all the inhabitants of Ai.

27Israel took for themselves only the livestock and the goods of that city, according to the LORD’s word which he commanded Joshua.

28So Joshua burned Ai and made it a heap forever, even a desolation, to this day.

29He hanged the king of Ai on a tree until the evening. At sundown, Joshua commanded, and they took his body down from the tree and threw it at the entrance of the gate of the city, and raised a great heap of stones on it that remains to this day.
