1 Samuel 19:9-17

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. So Michal let David down through the window: and he went, and fled, and escaped. And Michal took the teraphim, and laid it in the bed, and put a pillow of goats’ hair at the head thereof, and covered it with the clothes. And when Saul sent messengers to take David, she said, He is sick. And Saul sent the messengers to see David, saying, Bring him up to me in the bed, that I may slay him. And when the messengers came in, behold, the teraphim was in the bed, with the pillow of goats’ hair at the head thereof. And Saul said unto Michal, Why hast thou deceived me thus, and let mine enemy go, so that he is escaped? And Michal answered Saul, He said unto me, Let me go; why should I kill thee?
