Joshua 10:26-27

26And afterward Joshua smote them, and slew them, 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 setting of the sun, that Joshua commanded, and they took them down from the trees, and cast them into the cave in which they had been hid, and laid great stones upon the cave’s mouth, which remain until this very day.
