1 Samuel 19:12-17

12So Michal let David down through the window, and he fled away and escaped.

13Michal took an image and laid it on the bed and put a pillow of goats' hair at its head and covered it with the clothes.

14And when Saul sent messengers to take David, she said, "He is sick."

15Then Saul sent the messengers to see David, saying, "Bring him up to me in the bed, that I may kill him."

16And when the messengers came in, behold, the image was in the bed, with the pillow of goats' hair at its head.

17Saul said to Michal, "Why have you deceived me thus and let my enemy go, so that he has escaped?" And Michal answered Saul, "He said to me, 'Let me go. Why should I kill you?'"
