Part of the problem with the 'prophecies' that are found in the Tanakah, or old testament is that they were refering to something else entirely, and not supposed to be refering to the messiah. For example, the Isaiah passages, if you read it in context, were discussing the nation of Israel.
The Psalms were talking about David.. and were not a messanic prophecy.
Part of the problem also is translation, a change in expectations, and also the push to 'shoehorn' a random phrase into a prophecy. Those random phrases are sometimes mistranslated, taken out of context, and just plain misapplied to try to prove Jesus is the Messiah. It is easy to take random phrases in the bible, and then say it proves someone is the messiah. It has been done with elvis.
The translation also effects what is in the passages.. because many of the translators are inserting their bias of looking for the messiah into passages that it isn't appropriate. For example, Zechariah 9:9's
Jewish translation is
quote:
Rejoice Greatinly, Fair Zion; raise a shout, fair jerusalum! Lo, for you king is coming to you,. He is victorius, triumphant, yet humber, ridding on an ass. On a donkey fouled by a she-ass.
Notice, you pointed to a quote that has the world 'salvation' it in.
It is far more likely that this was shoehorned into place.
(I also don't see Jesus fullfilling the hope of banishing the chariots from Ephraim either). It is taking one phrase out of context, then writing to that phrase to make it into a prophecy.
YOu also have to wonder why SO many of these alledged prophecies that are allegedly a predictoin for the future were written in the past tense.
So many of the Isaiah passages, if you read just before or just after the passages that are insisted as being messanic, you will notice references to the people of israel, not a specfic person.
There also is the cultural differnce about what 'salvation' means to the Jews, and what a prophecy is to the Jews. For the Jewish religion, salvation is for THIS life, not the next one. Also, the prophecy is not so much a prediction for the future, but rather a message from god to warn, or to instruct. A sign for the future in prophecy was rather rare. There was a sense of immediancy, not for something 600 years or more into the future.
