It happened, when Saul was returned from following the Philistines, that it was told him, saying, Behold, David is in the wilderness of En Gedi.
"Behold, David is in the wilderness of Engedi"  (1 Samuel 24:1).  It is a measure of the persistent hatred of Saul that, as soon as he had chased the Philistines out of the country, he resumed his efforts to hunt down David and kill him.
