Isaiah 41:29

Behold, they are all vanity -They are unable to predict future events; they are unable to defend their friends, or to injure their enemies. This is the conclusion of the trial or debate (notes,Isaiah 41:1), and that conclusion is, that they were utterly destitute of strength, and that they were entirely unworthy of confidence and regard. Their molten images -(See the note atIsaiah 40:19). Are wind -Have no solidity or power. The doctrine of the whole chapter is, that confidence should be reposed in God, and in him alone. He is the friend of his people, and he is able to protect them.
