1 Samuel 26:2-4

Leeser(i) 2 Then arose Saul, and went down to the wilderness of Ziph, and with him were three thousand men chosen out of Israel, to seek David in the wilderness of Ziph. 3 And Saul encamped on the hill of Chachilah, which is before the desert by the way; but David abode in the wilderness, and he saw that Saul was coming after him into the wilderness. 4 David thereupon sent out spies, and understood that Saul was come for a certainty.
