1 Samuel 19:1-4

Saul told his son Jonathan and all his servants to kill David, but Jonathan liked David very much. So he warned David, “My father Saul is looking for a chance to kill you. Watch out in the morning. Hide in a secret place. I will go out and stand with my father in the field where you are hiding, and I’ll talk to him about you. Then I’ll let you know what I find out.” When Jonathan talked to Saul his father, he said good things about David. Jonathan said, “The king should do no wrong to your servant David since he has done nothing wrong to you. What he has done has helped you greatly.
