Joshua 8:28

24When Israel had finished killing all the inhabitants of Ai in the field, in the wilderness in which they pursued them, and they had all 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.

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.

30Then Joshua built an altar to the LORD, the God of Israel, on Mount Ebal,

31as Moses the servant of the LORD commanded the children of Israel, as it is written in the book of the law of Moses: an altar of uncut stones, on which no one had lifted up any iron. They offered burnt offerings on it to the LORD and sacrificed peace offerings.

32He wrote there on the stones a copy of Moses’ law, which he wrote in the presence of the children of Israel.
