I Samuel 23:25-29

When Saul and his men went to seek him, they told David. Therefore he went down to the rock, and stayed in the Wilderness of Maon. And when Saul heard that, he pursued David in the Wilderness of Maon. Then Saul went on one side of the mountain, and David and his men on the other side of the mountain. So David made haste to get away from Saul, for Saul and his men were encircling David and his men to take them. But a messenger came to Saul, saying, “Hurry and come, for the Philistines have invaded the land!” Therefore Saul returned from pursuing David, and went against the Philistines; so they called that place the Rock of Escape. Then David went up from there and dwelt in strongholds at En Gedi.
