1 Samuel 23:16 - 23:18
16 So Jonathan, Saul’s son, arose and went to David at Horesh and strengthened his hand in God. 17 And he said to him, “Do not be afraid, because the hand of Saul my father will not find you, and you will be king over Israel, and I will be second to you; and Saul my father knows that also.” 18 So the two of them cut a covenant before Yahweh; and David stayed at Horesh while Jonathan went to his house.
