There are arguments used to remove parts of Isaiah from the prophet by that name... using fulfilled prophecy.

> Is. 44:28 "...who says of Cyrus, 'He is my shepherd and will accomplish all that I please; he will say of Jerusalem, "Let it be rebuilt," and of the temple, "Let its foundations be laid.' "

> Is. 45:1 "This is what the LORD says to his anointed, to Cyrus, whose right hand I take hold of to subdue nations before him and to strip kings of their armor, to open doors before him so that gates will not be shut..."

We see these as a prophecy of the Persian king Cyrus - he who sent the Jews home from their Babylonian trials and authorized the rebuilding of Jerusalem and the temple. This is a remarkably specific prophecy if authentic. How do critics respond?

It all boils down, of course, to a denial of predictive prophecy, and barring recovery of a manuscript dating earlier than Cyrus, all either side can do is stick by their presumptions. Not that some haven't tried to go further; McKenzie, for example, argues:
> That Isaiah...could use the name of a king, in a language unknown to him, who ruled in a kingdom which did not exist...taxes probability too far. It is not a question of placing limits to the vision of prophecy but the limits of intelligibility; even if the name were by hypothesis meaningful to the prophet, it could not be meaningful to his readers or listeners.

But if a revelation had come to me in 1975, "Koresh will cause trouble in Waco," the name would be meaningful neither to me nor to anyone I told about it. The context of the words, as in Isaiah, would tell us that "Koresh" was a proper name of some sort; we might not know the proper name of what specifically (a person? a dog? a battleship?), but it would be quite clear even 20-25 years before the fact that someone or something called "Koresh" was involved.

This would be so even if the prophecy were delivered in 1875; it might have been less clear in, say, 1675, before Waco existed also, but even then, the context would help us ascertain what the word intended.
