Joshua 10:26

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 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.
