‘ And when these went into Micah's house, and fetched the graven image, the ephod, and the teraphim, and the molten image, the priest said to them, “What are you doing?” '
Up to this point the priest had been innocent and when he saw on their arrival that they were carrying the religious objects from the house of God he was surprised. He asked them what they thought they were doing. Note the repetition of ‘the graven image, and the ephod, and the teraphim, and the molten image' emphasising what their main purpose was and bringing out their sacrilege.
