'Rock' in the Bible

“There is no one holy like the Lord,There is no one besides You,There is no Rock like our God.

Then Saul and his men went to search for him. When David was told about it, he went down to the rock and stayed [there] in the Wilderness of Maon. When Saul heard it, he pursued David in the Wilderness of Maon.

So Saul returned from pursuing David and went to meet the Philistines; therefore they called that place the Rock of Escape.
