1 Samuel 23:13-18
English Standard Version
Chapter 23
13Then David and his men, who were about six hundred, arose and departed from Keilah, and they went wherever they could go. When Saul was told that David had escaped from Keilah, he gave up the expedition. 14And David remained in the strongholds in the wilderness, in the hill country of the wilderness of Ziph. And Saul sought him every day, but God did not give him into his hand.
15David saw that Saul had come out to seek his life. David was in the wilderness of Ziph at Horesh.
16And Jonathan, Saul 's son, rose and went to David at Horesh, and strengthened his hand in God.
17And he said to him, "Do not fear, for the hand of Saul my father shall not find you. You shall be king over Israel, and I shall be next to you. Saul my father also knows this."
18And the two of them made a covenant before the Lord. David remained at Horesh, and Jonathan went home.
