1 Samuel 26:2-4

Revised Standard Version

² So 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. ³ And Saul encamped on the hill of Hachi′lah, which is beside the road on the east of Jeshi′mon. But David remained in the wilderness; and when he saw that Saul came after him into the wilderness, ⁴ David sent out spies, and learned of a certainty that Saul had come.
