This is Isaiah"s fourth and last expos of the folly of idol worship (cf. Isaiah 40:19-20; Isaiah 41:6-7; Isaiah 44:9-20). How foolish it is to spend a lot of money and effort to make something that cannot care for itself much less its worshipper. It has no power to respond in any way, much less to save.
