Let all the nations be gathered together - Let them be assembled to give evidence, or to adduce proofs that their idols are worthy of confidence Isaiah 41:1.
Who among them can declare this? - Who among them hath predicted this state of things? Who has foretold the events which are now occurring? It is implied here, that Yahweh had done this, but none of the pagan gods had done it (see the note at Isaiah 41:21).
And show us former things - (see the note at Isaiah 41:22). The order of events, the manner in which one event shall succeed another. Not merely, who can declare one single event, but who can declare the succession, the order in which many events shall follow each other - a far more difficult thing than to declare one single future event. Neither had been done by the pagan; both had been done by God.
That they may be justified - That it may be demonstrated that they are what they pretend to be, and that they are worthy of the confidence of people. The word ‘justified’ here, is used in the sense of being right, or true; - let them in this manner show that their claims are just, and well founded.
Or let them hear, and say, It is truth - (See the note at Isaiah 41:26).
