1 Samuel 19:13

An image - “Teraphim” (see the margin), an image, or bust in human form, and as large as life, of a kind of household god, to the worship of which the Israelites, and especially women, were much addicted.

A pillow - It was probably a quilt or blanket of goats’ hair and of common use as a bed-covering. Whether Michal drew it over the head of the teraphim, as if for warmth, and so covered it, or whether she disposed it about the head so as to look like hair, is not clear.
