Joshua 10:25 (KJV)

And they did so, and brought forth those five kings unto him out of the cave, the king of Jerusalem, the king of Hebron, the king of Jarmuth, the king of Lachish, and the king of Eglon.

And it came to pass, when they brought out those kings unto Joshua, that Joshua called for all the men of Israel, and said unto the captains of the men of war which went with him, Come near, put your feet upon the necks of these kings. And they came near, and put their feet upon the necks of them.

And Joshua said unto them, Fear not, nor be dismayed, be strong and of good courage: for thus shall the Lord do to all your enemies against whom ye fight.

And afterward Joshua smote them, and slew them, and hanged them on five trees: and they were hanging upon the trees until the evening.

And 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 wherein they had been hid, and laid great stones in the cave’s mouth, which remain until this very day.
