Joshua 10:26-28 New Revised Standard Version (NRSV)
26 Afterward Joshua struck them down and put them to death, and he hung them on five trees. And they hung on the trees until evening. 27 At sunset Joshua commanded, and they took them down from the trees and threw them into the cave where they had hidden themselves; they set large stones against the mouth of the cave, which remain to this very day.
28 Joshua took Makkedah on that day, and struck it and its king with the edge of the sword; he utterly destroyed every person in it; he left no one remaining. And he did to the king of Makkedah as he had done to the king of Jericho.
