1 Samuel 26:2-4

2 Saul gathered 3000 of the best soldiers in Israel and went down to the desert of Ziph to search for David there.

3 Saul set up his camp by the road at Hakilah Hill, across from Jeshimon. David was out in the desert and saw that Saul had come out into the desert after him.

4 So David sent out spies to know for certain that Saul had come after him again.
