What was spoken was in response to Sleeppy, so it was about Sleeppy's view of messianic prophecy. In his/her view the prophecy was fulfilled majestically and divinely, one time only. Your view is that NT scriptures could have been altered later, and maybe even that this prophecy was written after the fact by Ezra rather than beforehand, and that would be okay with you. That is incompatible with the view Sleeppy has put forward where prophecies are divine predictions of specific events that are fulfilled and on a schedule. Besides that verse 28 also says "They will no longer be plundered by the nations," so I don't see why it matters if there was a bit of peace which was being purchased through taxes paid to the Seleucids. Its no kind of fulfillment of a specific prediction of peace, safety, no plundering by the nations.
It doesn't necessarily mean "No longer ever again" but could be referring to a finite time period. And I do believe there was no plundering during that 300+ year time span.
Do you deny that Ezekiel 36 is talking about the return of the Israelites from exile? Clearly Edom doesn't exist anymore, so it can't be referring to modern times now can it.
