1st Samuel 19:11

8 And there was war again: and David went out fighting the Philistines, causing great destruction among them; and they went in flight before him.

9 And an evil spirit from the Lord came on Saul, when he was seated in his house with his spear in his hand; and David made music for him.

10 And Saul would have sent his spear through him, pinning him to the wall, but he got away and the spear went into the wall: and that night David went in flight and got away.

11 Then in that night Saul sent men to David's house to keep watch on him so as to put him to death in the morning: and David's wife Michal said to him, If you do not go away to a safe place tonight you will be put to death in the morning.

12 So Michal let David down through the window, and he went in flight and got away.

13 Then Michal took the image and put it in the bed, with a cushion of goat's hair at its head, and she put clothing over it.

14 And when Saul sent men to take David, she said, He is ill.
