I don't think it's authoritative for Jews, let alone Christians.
But it's insightful to read about the Rabbinical understanding of the Messiah.
I read somewhere in one of the books of Sanhedrin, that the Messiah would come on the clouds of heaven (citing Daniel 7:13) if the Jewish people were worthy, and on an ass if they were not worthy (citing Zechariah?).
It's funny how they cite Daniel about the clouds of heaven, but not the "he will be given dominion, and authority and people's of all languages shall worship him." bit.
I think I understand why Christ thought they were unworthy.
