1 Samuel 19:8-14
19:8 Now once again there was war. So David went out to fight the Philistines. He defeated them thoroughly and they ran away from him.
19:9 Then an evil spirit from the Lord came upon Saul. He was sitting in his house with his spear in his hand, while David was playing the lyre.
19:10 Saul tried to nail David to the wall with the spear, but he escaped from Saul’s presence and the spear drove into the wall. David escaped quickly that night.
19:11 Saul sent messengers to David’s house to guard it and to kill him in the morning. Then David’s wife Michal told him, “If you do not save yourself tonight, tomorrow you will be dead!”
19:12 So Michal lowered David through the window, and he ran away and escaped.
19:13 Then Michal took a household idol and put it on the bed. She put a quilt made of goat’s hair over its head and then covered the idol with a garment.
19:14 When Saul sent messengers to arrest David, she said, “He’s sick.”
