1 Samuel 19:11-18

11Saul also sent messengers to David’s house, to watch him, and to slay him in the morning: and Michal David’s wife told him, saying, If thou dost not save 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 head, and covered it with a cloth.1 14And when Saul sent messengers to take David, she said, He is sick. 15And Saul sent the messengers again to see David, saying, Bring him to me in the bed, that I may slay him. 16And when the messengers had come in, behold, there was an image in the bed, with a pillow of goats’ hair for his head. 17And Saul said to Michal, Why hast thou deceived me so, and sent away my enemy, that he hast escaped? And Michal answered Saul, He said to me, Let me go; why should I kill thee?

18So David fled, and escaped, and came to Samuel to Ramah, and told him all that Saul had done to him. And he and Samuel went and dwelt in Naioth.
