1 Samuel 19:1-4

Saul told his son Jonathan and all the attendants to kill David. But Jonathan had taken a great liking to David and warned him, “My father Saul is looking for a chance to kill you. Be on your guard tomorrow morning; go into hiding and stay there. I will go out and stand with my father in the field where you are. I’ll speak to him about you and will tell you what I find out.” Jonathan spoke well of David to Saul his father and said to him, “Let not the king do wrong to his servant David; he has not wronged you, and what he has done has benefited you greatly.
