1 Samuel 23:13–17

Then David and his men, who were about six hundred, arose and departed from Kei’lah, and they went wherever they could go. When Saul was told that David had escaped from Kei’lah, he gave up the expedition. And 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. And David was afraid because Saul had come out to seek his life. David was in the Wilderness of Ziph at Horesh.  And Jonathan, Saul’s son, rose, and went to David at Horesh, and strengthened his hand in God.  And he said to him, “Fear not; 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.”
