“In Isa. 54.16, Yahweh is explicitly mentioned as the creator of both the copperwork and his work: 'See it is I who have created the smith who blows the fire of coals, and produces a weapon fit for its purposes'. Such an involvement of Yahweh is never mentioned elsewhere for other crafts or human activities. (p. 394)
