(29) They are all . . . their works . . .--The first pronoun refers to the idols themselves, the second to the idolaters who make them. In "confusion" we have the familiar tohu.

41:21-29 There needs no more to show the folly of sin, than to bring to notice the reasons given in defence of it. There is nothing in idols worthy of regard. They are less than nothing, and worse than nothing. Let the advocates of other doctrines than that of salvation through Christ, bring their arguments. Can they tell of a cure for human depravity? Jehovah has power which cannot be withstood; this he will make appear. But the certain knowledge of the future must be only with Jehovah, who fulfils his own plans. All prophecies, except those of the Bible, have been uncertain. In the work of redemption the Lord showed himself much more than in the release of the Jews from Babylon. The good tidings the Lord will send in the gospel, is a mystery hid from ages and generations. A Deliverer is raised up for us, of nobler name and greater power than the deliverer of the captive Jews. May we be numbered among his obedient servants and faithful friends.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.
