Teraphim, mentioned many times throughout the Old Testament, were small statues, figurines, or talismans representing household gods.  They were common in Syria, Palestine, and even Israel and used for divination.  It is unclear how they were used (i.e. how the owner “consulted” them) nor what their appearance was (likely humanoid).  They were likely kept in a household enclosed in some sort of shrine and/or worn about the body.
