1 Samuel 19:1-10 NLT

1 Saul now urged his servants and his son Jonathan to assassinate David. But Jonathan, because of his close friendship with David,
2 told him what his father was planning. "Tomorrow morning," he warned him, "you must find a hiding place out in the fields.
3 I'll ask my father to go out there with me, and I'll talk to him about you. Then I'll tell you everything I can find out."
4 The next morning Jonathan spoke with his father about David, saying many good things about him. "Please don't sin against David," Jonathan pleaded. "He's never done anything to harm you. He has always helped you in any way he could.
5 Have you forgotten about the time he risked his life to kill the Philistine giant and how the LORD brought a great victory to Israel as a result? You were certainly happy about it then. Why should you murder an innocent man like David? There is no reason for it at all!"
6 So Saul listened to Jonathan and vowed, "As surely as the LORD lives, David will not be killed."
7 Afterward Jonathan called David and told him what had happened. Then he took David to see Saul, and everything was as it had been before.
8 War broke out shortly after that, and David led his troops against the Philistines. He attacked them with such fury that they all ran away.
9 But one day as Saul was sitting at home, the tormenting spirit from the LORD suddenly came upon him again. As David played his harp for the king,
10 Saul hurled his spear at David in an attempt to kill him. But David dodged out of the way and escaped into the night, leaving the spear stuck in the wall.
