1Sam 19:11-17

11Saul sent messengers to David's house to keep watch over him, planning to kill him in the morning. David's wife Michal told him, “If you do not save your life tonight, tomorrow you will be killed.”12So Michal let David down through the window; he fled away and escaped.13Michal took an idol and laid it on the bed; she put a net of goats' hair on its head, and covered it with the clothes.14When Saul sent messengers to take David, she said, “He is sick.”15Then Saul sent the messengers to see David for themselves. He said, “Bring him up to me in the bed, that I may kill him.”16When the messengers came in, the idol was in the bed, with the covering of goats' hair on its head.17Saul said to Michal, “Why have you deceived me like this, and let my enemy go, so that he has escaped?” Michal answered Saul, “He said to me, ‘Let me go; why should I kill you?’ ”
