Passage
Behold they are all in the wrong, and their works are vain: their idols are wind and vanity.
Behold they are all in the wrong, and their works are vain: their idols are wind and vanity.
Isaiah 41:27 The first shall say to Sion: Behold they are here, and to Jerusalem I will give an evangelist.
Isaiah 41:28 And I saw, and there was no one even among them to consult, or who, when I asked, could answer a word.
Isaiah 41:29 Behold they are all in the wrong, and their works are vain: their idols are wind and vanity.
The verse centers on "behold", "wrong", "works", "vain", "idols", "wind", and "vanity". It is saying that the verse draws attention to "behold" and "wrong", so its meaning should be read from those terms before moving to application.
The prior verse says "And I saw and there was no...", giving immediate footing for "behold" and "wrong". In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "behold" and "wrong" with trust shaped by these words, not by a vague optimism outside the passage.
