Joshua 8:24-26

24Now when Israel had finished killing all the inhabitants of Ai in the field in the wilderness where they pursued them, and all of them had 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.

25So 1all who fell that day, both men and women, were twelve thousand--all the 2people of Ai.

26For Joshua 3did not withdraw his hand with which he reached out with the sword until he had 4utterly destroyed all the inhabitants of Ai.
