1 Samuel 23:14-18

14And David abode in the wilderness in strongholds, and abode in the mountain in the wilderness of Ziph. And Saul sought him every day, but 1God did not give him into his hand.

15And David saw that Saul had come out to seek his life; and David was in the wilderness of Ziph in a wood.

16And Jonathan Saul's son arose, and went to David into the wood, and strengthened his hand in 2God.

17And he said to him, Fear not; for the hand of Saul my father will not find thee; and thou shalt be king over Israel, and I shall be next to thee; and that also Saul my father knows.

18And they two made a covenant before Jehovah; and David abode in the wood, and Jonathan went to his house.
