1 Samuel 19:7-10

Afterward Jonathan called David and told him what had happened. Then he brought David to Saul, and David served in the court as before. War broke out again after that, and David led his troops against the Philistines. He attacked them with such fury that they all ran away. But one day when Saul was sitting at home, with spear in hand, the tormenting spirit from the LORD suddenly came upon him again. As David played his harp, Saul hurled his spear at David. But David dodged out of the way, and leaving the spear stuck in the wall, he fled and escaped into the night.
