Joshua 10:26-27

26And afterwards Joshua smote them, and put them to death, and hanged them on five trees; and they were hanging upon the trees until the evening.

27And it came to pass at the time of the going down of the sun, that Joshua commanded, and they took them down off the trees, and cast them into the cave where they had been hid, and laid great stones before the cave's mouth, [which remain] to this very day.
