1 Samuel 19:11-15

Saul also sent messengers unto David’s house, to watch him, and to slay him in the morning: and Michal David’s wife told him, saying, If thou save not thy life to night, to morrow thou shalt be slain.

So Michal let David down through a window: and he went, and fled, and escaped.

And Michal took an image, and laid it in the bed, and put a pillow of goats’ hair for his bolster, and covered it with a cloth.

And when Saul sent messengers to take David, she said, He is sick.

And Saul sent the messengers again to see David, saying, Bring him up to me in the bed, that I may slay him.
