Joshua 8:23-29

23But they took the king of Ai alive and brought him to Joshua.

24When Israel had finished killing all the inhabitants of Ai in the field in the wilderness where they pursued them, and they had all fallen by the edge of the sword until they were destroyed, then all Israel returned to Ai and struck it with the edge of the sword.

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

26For Joshua did not withdraw his hand with which he stretched out the spear until he had utterly destroyed all the inhabitants of Ai.

27Israel took only the livestock and the spoil of that city as plunder for themselves, according to the word of the Lord which He had commanded Joshua.

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

29He hanged [the body of] the king of Ai on a tree [leaving it there] until evening; at sunset Joshua gave a command and they took the body down from the tree and dumped it at the entrance of the city gate, and piled a great heap of stones over it that stands to this day.
