1 Samuel 19:12-17

12And Michal let David down through a window; and he went, and fled and escaped.

13And Michal took the image, and laid it in the bed, and put the net of goats' [hair] at its head, and covered it with the coverlet.

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

15And Saul sent the messengers to see David, saying, Bring him up to me in the bed, that I may put him to death.

16And the messengers came in, and behold, the image was in the bed, and the net of goats' [hair] at its head.

17Then Saul said to Michal, Why hast thou deceived me so, and sent away mine enemy, that he is escaped? And Michal said to Saul, He said to me, Let me go; why should I slay thee?
