1 Samuel 23:24-29

So the men of Ziph returned home ahead of Saul. Meanwhile, David and his men had moved into the wilderness of Maon in the Arabah Valley south of Jeshimon. When David heard that Saul and his men were searching for him, he went even farther into the wilderness to the great rock, and he remained there in the wilderness of Maon. But Saul kept after him in the wilderness. Saul and David were now on opposite sides of a mountain. Just as Saul and his men began to close in on David and his men, an urgent message reached Saul that the Philistines were raiding Israel again. So Saul quit chasing David and returned to fight the Philistines. Ever since that time, the place where David was camped has been called the Rock of Escape. David then went to live in the strongholds of En-gedi.
