'Cave' in the Bible

So David left there and escaped to the cave of Adullam. When his brothers and the rest of his father's family learned about it, they went down there to him.

He came to the sheepfolds by the road, where there was a cave. Saul went into it to relieve himself. Now David and his men were sitting in the recesses of the cave.

David restrained his men with these words and did not allow them to rise up against Saul. Then Saul left the cave and started down the road.

Afterward David got up and went out of the cave. He called out after Saul, "My lord, O king!" When Saul looked behind him, David kneeled down and bowed with his face to the ground.

Today your own eyes see how the Lord delivered you -- this very day -- into my hands in the cave. Some told me to kill you, but I had pity on you and said, 'I will not extend my hand against my lord, for he is the Lord's chosen one.'
