1 Samuel 19:8-11

8 ¶ And there was war again: and David went out, and fought with the Philistines, and slew them with a great slaughter; and they fled from him. 9 And the evil spirit from the Lord was upon Saul, as he sat in his house with his javelin in his hand: and David played with his hand. 10 And Saul sought to smite David even to the wall with the javelin; but he slipped away out of Saul’s presence, and he smote the javelin into the wall: and David fled, and escaped that night. 11 Saul also 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 shalt be slain.
