Joshua 8:23-29

23but they captured the king of Ai alive and brought him to Joshua.

24When Israel had finished killing everyone living in Ai who had pursued them into the open country, and when every last one of them had fallen by the sword, all Israel returned to Ai and struck it down with the sword.

25The total of those who fell that day, both men and women, was twelve thousand — all the people of Ai.

26Joshua did not draw back his hand that was holding the javelin until all the inhabitants of Ai were completely destroyed.

27Israel plundered only the cattle and spoil of that city for themselves, according to the Lord’s command that he had given Joshua.

28Joshua burned Ai and left it a permanent ruin, still desolate today.

29He hung the body of the king of Ai on a tree until evening, and at sunset Joshua commanded that they take his body down from the tree. They threw it down at the entrance of the city gate and put a large pile of rocks over it, which still remains today.
