1 Samuel 23:13-18 New Revised Standard Version (NRSV)

13 Then David and his men, who were about six hundred, set out and left Keilah; they wandered wherever they could go. When Saul was told that David had escaped from Keilah, he gave up the expedition. 14 David remained in the strongholds in the wilderness, in the hill country of the Wilderness of Ziph. Saul sought him every day, but the Lord did not give him into his hand.

David Eludes Saul in the Wilderness

15 David was in the Wilderness of Ziph at Horesh when he learned that Saul had come out to seek his life. 16 Saul’s son Jonathan set out and came to David at Horesh; there he strengthened his hand through the Lord. 17 He said to him, “Do not be afraid; for the hand of my father Saul shall not find you; you shall be king over Israel, and I shall be second to you; my father Saul also knows that this is so.” 18 Then the two of them made a covenant before the Lord; David remained at Horesh, and Jonathan went home.
