1 Samuel 18:10-12

The next day an evil spirit from God rushed upon Saul, and he prophesied in his house. David was playing the harp as he usually did, but Saul had a spear in his hand. He threw the spear, thinking, “I’ll pin David to the wall.” But David escaped from him twice. The LORD was with David but had left Saul. So Saul was afraid of David.
