Isaiah 44:9-12

9Those who fashion idols are empty. Their precious things do not profit. Their witnesses do not see or know, so they will be put to shame.

10Who fashions a god or casts an idol for no profit?

11Behold, all his friends will be ashamed, for the craftsmen are only human. Let them all assemble. Let them stand up. Let them dread. Let them be put to shame together.

12The blacksmith takes a tool and works with it over the coals, fashioning it with hammers and working it with his strong arm. Yet when he is hungry, his strength fails. When he drinks no water, he gets tired.
