'Cave's' in the Bible

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

At sunset Joshua gave a command, and they took the bodies down from the trees and threw them into the cave where the kings had hidden themselves, and placed large stones over the mouth of the cave, [where they remain] to this very day.

On the way he came to the sheepfolds where there was a cave; and Saul went in to relieve himself. Now David and his men were sitting in the cave’s innermost recesses.
