1 Samuel 19:1-7 New American Bible (Revised Edition) (NABRE)
Persecution of David. 1 Saul discussed his intention to kill David with his son Jonathan and with all his servants. But Saul’s son Jonathan, who was very fond of David, 2 told him: “My father Saul is trying to kill you. Therefore, please be on your guard tomorrow morning; stay out of sight and remain in hiding. 3 I, however, will go out and stand beside my father in the countryside where you are, and will speak to him about you. If I learn anything, I will let you know.”
4 Jonathan then spoke well of David to his father Saul, telling him: “The king should not harm his servant David. He has not harmed you, but has helped you very much by his deeds.[a] 5 When he took his life in his hands and killed the Philistine, and the Lord won a great victory for all Israel, you were glad to see it. Why, then, should you become guilty of shedding innocent blood by killing David without cause?” 6 Saul heeded Jonathan’s plea and swore, “As the Lord lives, he shall not be killed.” 7 So Jonathan summoned David and repeated the whole conversation to him. He then brought David to Saul, and David served him as before.
