1 Samuel 23:14-18
English Standard Version
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.
