Isaiah 44:9

(Verse 6 and following) This is what the Lord, the king of Israel and his redeemer, the Lord of hosts, says: I am the first and I am the last, and there is no God besides me. Who is like me? Let him call and declare, and lay out the order for me, since I established the ancient people: what is coming and what will happen, let them declare to them. Do not be afraid, nor be troubled: from that time I have made you hear and announced it; you are my witnesses. Is there any God besides me, and a creator whom I do not know? All the idols of the nations are worthless, and the things they love do not profit them. They themselves are witnesses to their own worthlessness, for they do not see or understand, so that they may be put to shame. Who formed a god or cast an idol that is profitable for nothing? Look, all his companions shall be put to shame; the craftsmen are mere men. Let them all assemble, let them stand forth. They shall be terrified; they shall be put to shame together. The blacksmith takes a tool and works it with the coals; he fashions it with hammers and works it with his strong arm. He will be hungry and will become weak, he will not drink water, and he will grow weary. The carpenter extends the rule (or the form), he shapes it on the plane, he forms it with angles, and rounds it off with a compass. And he makes an image of a man, like a handsome man dwelling in a house. He cuts down cedars, he takes an oak, and a tree that stood among the woods. He plants a pine, which the rain nourishes, and it becomes fuel for men. He takes from them, and warms himself; he kindles it, and bakes bread. But the rest of it he made into a god and worshipped; he made an idol and bowed down to it. He burned half of it in the fire and cooked meat on it; he roasted a stew and ate it, and then he was satisfied. He warmed himself and said, 'Ah! […]

Isaiah sees that in the ensuing time a very great number of people will arise who all "will be ashamed" and who will cease from their continual error. They will be ashamed and hide their faces. If they persist in their error, however, they will be given over to destruction at the time of judgment. But this word is also for those of us now in the present.

Second, he shows the unsuitableness of their witnesses: the makers (plastae) of idols, are all of them nothing, of no power, above: all nations are before him as if they had no being at all (Isa 40:17), or because they do not obtain their intention, …

They that make a graven image are all of them vanity,....

We appeal to themselves whether it be not a silly sottish thing to expect any good from gods of their own making: They are their own witnesses, witnesses against themselves, if they would but give their own consciences leave to deal faithfully with them, that they are blind and ignorant in doing thus.
