1 Samuel 19:13

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.

Ver. 13. And Michal took an image.] Either a statue, David's own statue, or else some superstitious image (the Hebrew is teraphim) which she kept secretly, as Rachel had done, David knowing nothing of it. Some have probably gathered that Michal, though a good wife, yet was no good woman: both because she had an image in the house, and afterward she mocked David for his devotion.

And put a pillow of goats' hair.] Which might make the messengers believe it was the hair of David's head. This she did that she might gain more time for her fleeing husband. Or such a pillow, as for ease and warmth.
