I would consider that a reference to Baha`u'llah actually, expecially when it's in context
6 For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, [
b] Mighty God,
Everlasting Father, Prince of Peace.
7 Of the increase of his government and peace
there will be no end.
He will reign on David's throne
and over his kingdom,
establishing and upholding it
with justice and righteousness
from that time on and forever.
The zeal of the LORD Almighty
will accomplish this.
The original TaNakh says:
9,5 For a child is born unto us, a son is given unto us; and the government is upon his shoulder; and his name is called Pele-joez-el-gibbor-Abi-ad-sar-shalom; 9,6 That the government may be increased, and of peace there be no end, upon the throne of David, and upon his kingdom, to establish it, and to uphold it through justice and through righteousness from henceforth even for ever. The zeal of the LORD of hosts doth perform this. {P}
(Nev'im (Prophets), Yeshayahu (Isaiah))
Some take this to mean the son that was born to the king of Judea at the time of Yeshayahu. The implication being that it was a big "suck up" on the part of the prophet. That particular prince never lived up to the hype.
