1 Samuel 19:12-18

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?’ ” Now David fled and escaped and came to Samuel at Ramah, and told him all that Saul had done to him. And he and Samuel went and stayed in Naioth.
