I Samuel 19:12-18

So Michal let David down through a window. And he went and fled and escaped. And Michal took an image and laid it in the bed, put a cover of goats’ hair for his head, and covered it with clothes. So when Saul sent messengers to take David, she said, “He is sick.” Then Saul sent the messengers back to see David, saying, “Bring him up to me in the bed, that I may kill him.” And when the messengers had come in, there was the image in the bed, with a cover of goats’ hair for his head. Then Saul said to Michal, “Why have you deceived me like this, and sent my enemy away, so that he has escaped?” And Michal answered Saul, “He said to me, ‘Let me go! Why should I kill you?’ ” So David fled and escaped, and went to Samuel at Ramah, and told him all that Saul had done to him. And he and Samuel went and stayed in Naioth.
