1 Samuel 19:9-11

And an evil spirit from Jehovah was upon Saul, as he sat in his house with his spear in his hand; and David was playing with his hand. And Saul sought to smite David even to the wall with the spear; but he slipped away out of Saul’s presence, and he smote the spear into the wall: and David fled, and escaped that night. And Saul sent messengers unto David’s house, to watch him, and to slay him in the morning: and Michal, David’s wife, told him, saying, If thou save not thy life to-night, to-morrow thou wilt be slain.
