Isaiah 41:29

“Behold, they are all vanity, &c.] 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…”

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

“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…”

“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, Gen 1:2. Next: Isaiah Chapter 42”

“they are all: Isa 41:24, Isa 44:9-20; Psa 115:4-8, Psa 135:15-18; Jer 10:2-16; Hab 2:18 wind: Jer 5:13 Next: Isaiah Chapter 42”

“This closing declaration of Jehovah terminates with similar words of wrath and contempt to those with which the judicial process ended in Isa 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 Eze 6:6; Jer 1:16) of the idolaters - in other words, the idols themselves - a parallel expression to נסכּיהם (from נסך, as in Isa 48:5 = massēkhâh, Isa 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…”
