The word here translated “pillow” does not appear elsewhere in the OT, and its meaning is uncertain. The fact that the “pillows” of ancient times were usually solid, and made of wood, clay, stone, or metal (see on Gen. 28:11), suggests that the object here referred to was something other than a “pillow.” It may have been a sort of wig made of black goat’s hair attached to the head of the image, in imitation of human hair.
An image.
Heb. teraphim (see on Gen. 31:19; Lev. 19:31). An image of sufficient size to be mistaken for a man is most unusual.
