'Cave's' in the Bible

Joshua said, “Roll large stones against the mouth of the cave, and assign men by it to guard them,

Joshua said, "Open the cave's mouth and bring the five kings out of the cave to me."

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.
