Behold, they are all vanity; their works are nothing: their molten images are wind and confusion.

Behold, all of them, their works are vanity and nought; their molten images are wind and confusion.

Behold they are all in the wrong, and their works are vain: their idols are wind and vanity.

Behold, they are all vanity, their works are nought, their molten images are wind and emptiness.

Lo, all of them are vanity, Nought are their works, Wind and emptiness their molten images!'

Truly they are all nothing, their works are nothing and of no value: their metal images are of no more use than wind.

Behold, they are all unjust, and their works are empty. Their idols are wind and emptiness.

Ecce onmes vanitas, et defectus opera; eorum; ventus et chaos simulachra eorum.

Behold, they are all vanity. After having spoken of idols, he makes the same statement as to their worshippers; as it is also said, "They who make them, and all that trust in them, are like them." (Psalm 115:8.) Thus he shews that all superstitious persons are full of "vanity," and have no judgment or reason. They cannot, indeed, believe this; for, inflated with pride, they look upon themselves as men of the highest ability, and despise us as stupid and ignorant of the affairs of men, when compared with themselves. With what pride do the Papists and their learned doctors scorn us! With what haughtiness did the Romans in ancient times despise the Jews! But we need not spend time on such pride, for in this passage God condemns them all for "vanity." Their works are a failure. He gives the name of "works" both to the images which superstitious men make for themselves, and to all false worship, which has no end or measure, and in which every person desires to be a master and teacher of religion. He pronounces all of them to be a "failure," that is, of no value. He declares this still more plainly, when he says, that they are wind and chaos, that is, confusion; for I explain thv (tohu) in the same sense that it has in the first chapter of Genesis, where Moses says that "the earth was at first shapeless and confused." (Genesis 1:2.) This passage against idolaters ought to be carefully studied; for they think that images were appointed to preserve religion, and that minds are kindled by the sight of them, as by the visible presence of God. They think that they are the books of the ignorant and unlearned, who cannot be instructed by the reading of the Scriptures. But the Spirit of God here declares that it is a confused and shapeless thing, that is, because it disturbs and retains in superstition the minds of men; and indeed all true knowledge that exists among men is choked and quenched by this worship of idols. In short, he teaches that all images, and the homage that is paid to them, and they who have made and follow them, are mere vanity, and that we may safely condemn them.

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 at Isaiah 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. He will deliver them from the hand of all their enemies; and he will be always their God, protector, and guide. The idols of the pagan have no power; and it is folly, as well as sin, to trust in them, or to suppose that they can aid their friend.
It may be added, also, that it is equally vain to trust in any being for salvation but God. He only is able to protect and defend us; and it is a source of unspeakable consolation now, as it was in times past, that he is the friend of his people; and that, in times of deepest darkness and distress, he can raise up deliverers, as he did Cyrus, and will in his own way and time rescue his people from all their calamities.

Behold, they are all vanity,.... Both the idols and the worshippers of them; in vain they claim the title of deity, to which they have no right; and in vain do men worship them, since they receive no benefit by them:
their works are nothing; they can do nothing, neither good nor evil; nothing is to be hoped or feared from them, and the worship given them is of no avail; nothing is got by it; it is all useless and insignificant, yea, pernicious and harmful:
their molten images are wind and confusion: though they are made of cast metal, yet setting aside the costly matter of which they are made, they are of no more solidity, efficacy, and use, than the wind; and are like the chaos of the first earth, mere "tohu" and "bohu", one of which words is here used, without form and void, having no form of deity on them; and therefore men are directed to turn themselves from them, and behold a most glorious Person, worthy of worship and praise, described in the beginning of the next chapter, "behold my servant", &c.

confusion--"emptiness" [BARNES].
God's description of His character (Isaiah 42:1-4). God addresses Him directly (Isaiah 42:5-7). Address to the people to attend to the subject (Isaiah 42:8-9). Call to all, and especially the exile Jews to rejoice in the coming deliverance (Isaiah. 42:10-25).

This closing declaration of Jehovah terminates with similar words of wrath and contempt to those with which the judicial process ended in Isaiah 41:24. "See them all, vanity; nothingness are their productions, wind and desolation their molten images." מעשׂיהם are not the works of the idols, but, as the parallel shows, the productions (plural, as in Ezekiel 6:6; Jeremiah 1:16) of the idolaters - in other words, the idols themselves - a parallel expression to נסכּיהם (from נסך, as in Isaiah 48:5 = massēkhâh, Isaiah 42:17). אפס און is an emotional asyndeton (Ges. 155, 1, a). The address is thus rounded off by returning to the idolaters, with whom it first started. The first part, vv. 1-24, contains the judicial pleadings; the second part, Isaiah 41:25., recapitulates the evidence and the verdict.

Behold - This is the conclusion of the dispute, but under these he comprehends all images whatsoever. Wind - Empty and unsatisfying things. Confusion - Confused and useless things, like that rude heap in the beginning of God's creation, of which this very word is used, Genesis 1:2.
