1 Samuel 19:11 KJV

9And 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.

10And 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.

11Saul 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.

12So Michal let David down through a window: and he went, and fled, and escaped.

13And Michal took an image, and laid it in the bed, and put a pillow of goats’ hair for his bolster, and covered it with a cloth.
