1 Samuel 26:1-4

1Then the Ziphites came to Saul at Gibeah, saying, "Is not David hiding himself on the hill of Hachilah, which is on the east of Jeshimon?"

2So Saul arose and went down to the wilderness of Ziph with three thousand chosen men of Israel to seek David in the wilderness of Ziph.

3And Saul encamped on the hill of Hachilah, which is beside the road on the east of Jeshimon. But David remained in the wilderness. When he saw that Saul came after him into the wilderness,

4David sent out spies and learned that Saul had indeed come.
