1 Samuel 23:16-18

MSB(i) 16 And Saul’s son Jonathan came to David in Horesh and strengthened his hand in God, 17 saying, “Do not be afraid, for my father Saul will never lay a hand on you. And you will be king over Israel, and I will be your second-in-command. Even my father Saul knows this is true.” 18 So the two of them made a covenant before the LORD. And David remained in Horesh, while Jonathan went home.
