1 Samuel 18:10-12

The very next day a tormenting spirit from God overwhelmed Saul, and he began to rave in his house like a madman. David was playing the harp, as he did each day. But Saul had a spear in his hand, and he suddenly hurled it at David, intending to pin him to the wall. But David escaped him twice. Saul was then afraid of David, for the LORD was with David and had turned away from Saul.
