1 Samuel 19:9-17

Now there was an evil spirit from the LORD on Saul as he was sitting in his house with his spear in his hand, and David was playing the harp with his hand. Saul tried to pin David to the wall with the spear, but he slipped away out of Saul’s presence, so that he stuck the spear into the wall. And David fled and escaped that night. Then Saul sent messengers to David’s house to watch him, in order to put him to death in the morning. But Michal, David’s wife, told him, saying, “If you do not save your life tonight, tomorrow you will be put to death.” So Michal let David down through a window, and he went out and fled and escaped. Michal took the household idol and laid it on the bed, and put a quilt of goats’ hair at its head, and covered it with clothes. When Saul sent messengers to take David, she said, “He is sick.” Then Saul sent messengers to see David, saying, “Bring him up to me on his bed, that I may put him to death.” When the messengers entered, behold, the household idol was on the bed with the quilt of goats’ hair at its head. So Saul said to Michal, “Why have you deceived me like this and let my enemy go, so that he has escaped?” And Michal said to Saul, “He said to me, ‘Let me go! Why should I put you to death?’ ”
