1 Samuel 23:15-18

While David was at Horesh in the Desert of Ziph, he learned that Saul had come out to take his life. And Saul’s son Jonathan went to David at Horesh and helped him find strength in God. “Don’t be afraid,” he said. “My father Saul will not lay a hand on you. You will be king over Israel, and I will be second to you. Even my father Saul knows this.” The two of them made a covenant before the LORD. Then Jonathan went home, but David remained at Horesh.
