Joshua 8:21-22

21When 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 1killed the men of Ai.

222The others came out from the city to confront them, so that they were trapped in the midst of Israel, 3some on this side and some on that side; and they 4killed them until there was not 5one 6left who escaped or survived.
