1 Samuel 26:13

And the Ziphites came unto Saul to Gibeah, saying, Doth not David hide himself in the hill of Hachilah, which is before Jeshimon?

Then Saul arose, and went down to the wilderness of Ziph, having three thousand chosen men of Israel with him, to seek David in the wilderness of Ziph.

And Saul pitched in the hill of Hachilah, which is before Jeshimon, by the way. But David abode in the wilderness, and he saw that Saul came after him into the wilderness.

David therefore sent out spies, and understood that Saul was come in very deed.
