Joshua 8:18-29

Then the LORD said to Joshua, “Stretch out the javelin that is in your hand toward Ai, for I will give it into your hand.” So Joshua stretched out the javelin that was in his hand toward the city. The men in ambush rose quickly from their place, and when he had stretched out his hand, they ran and entered the city and captured it, and they quickly set the city on fire. When the men of Ai turned back and looked, behold, the smoke of the city ascended to the sky, and they had no place to flee this way or that, for the people who had been fleeing to the wilderness turned against the pursuers. When Joshua and all Israel saw that the men in ambush had captured the city and that the smoke of the city ascended, they turned back and slew the men of Ai. The others came out from the city to encounter them, so that they were trapped in the midst of Israel, some on this side and some on that side; and they slew them until no one was left of those who survived or escaped. But they took alive the king of Ai and brought him to Joshua. Now when Israel had finished killing all the inhabitants of Ai in the field in the wilderness where they pursued them, and all of them were 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. All who fell that day, both men and women, were 12,000—all the people of Ai. For Joshua did not withdraw his hand with which he stretched out the javelin until he had utterly destroyed all the inhabitants of Ai. Israel took only the cattle and the spoil of that city as plunder for themselves, according to the word of the LORD which He had commanded Joshua. So Joshua burned Ai and made it a heap forever, a desolation until this day. He hanged the king of Ai on a tree until evening; and at sunset Joshua gave command and they took his body down from the tree and threw it at the entrance of the city gate, and raised over it a great heap of stones that stands to this day.
