1 Samuel 23:25-28

25and Saul and his men went to look for him. When David was told about it, he went down to the rock and stayed in the Wilderness of Maon. Saul heard of this and pursued David there.

26Saul went along one side of the mountain and David and his men went along the other side. Even though David was hurrying to get away from Saul, Saul and his men were closing in on David and his men to capture them.

27Then a messenger came to Saul saying, “Come quickly, because the Philistines have raided the land!”

28So Saul broke off his pursuit of David and went to engage the Philistines. Therefore, that place was named the Rock of Separation.
