1 Samuel 19:11-14

Saul therefore sent his guards to David's house to watch him, that he might be killed in the morning. And when Michol, David's wife, had told him this, saying: Unless thou save thyself this night, to morrow thou wilt die:

She let him down through a window. And he went and fled away, and escaped.

And Michol took an image, and laid it on the bed, and put a goat's skin, with the hair at the head of it, and covered it with clothes.
