1 Samuel 23:24-29

24 So they left and returned to Ziph ahead of Saul. David and his men were in the wilderness of Maon, in a desolate valley in the southern part of the Judean wilderness.
25 Saul and his men set out to look for David, but he heard about it and went to a rocky hill in the wilderness of Maon and stayed there. When Saul heard about this, he went after David.
26 Saul and his men were on one side of the hill, separated from David and his men, who were on the other side. They were hurrying to get away from Saul and his men, who were closing in on them and were about to capture them.
27 Just then a messenger arrived and said to Saul, "Come back at once! The Philistines are invading the country!"
28 So Saul stopped pursuing David and went to fight the Philistines. That is why that place is called Separation Hill.
29 David left and went to the region of Engedi, where he stayed in hiding.
