The problem with the Messiah was that to most people back then, you really would have assumed him to be a normal person, and would have to be aware of the prophecies, which were ambigious to an extent.
THE BIG problem is that the Yahudi expected him to come and conquer the Romans, he did not do that so they thought he was a phony.
As a bit later there was a member of Yahudi who led a revolt agaisnt the Romans and this led them to think he was the prophecized Messiah, granted I don't think his name was "Joshua" which was the prophecized name of savior, but when he failed the revolt, I belive they recorded his name as Yeshu which was actually an insulting term, not equal to Joshua/Yoshua. Later during the middle ages onwards they recorded the Messiahs name in the insulting Yeshu a different name from Joshua, which is probably where the corruption Jesus came from. This is when they went full on agaisnt Christainity in argumentive writtings and documents but as mentioned in this thread there were various forms of Christainity, there was iconic heavy moor version, and there was the version the Romans put together which had elements like the trinity and all of that stuff. I think this is the one Israelities really hated. I know of a tribe of descedants of Ishmeal who were lucky enough to remain unbothered on their land for a bit over 1000 years to this day. They said from their perspective, Christain Moors, Muslims and Isrealites who followed the Mosiac Law pretty much got a long fairly well finding common ground in Abraham, but Persian, Roman and Turkish conquers would use and inflate the religious differences as a pretext to war and conquest. Its pretty interesting getting the view from the tribe, having stories of David going to their ancestors for help and advice since they lived near the border of now abandoned Isrealite territory.
Regardless the overthrow of Rome was suppose to be for the end time of all ages, if that would imply this age and the decendants of Romans rule a majority of territory now, even if a small percentage of them knew or belived it to be true would they teach in any of their religious structures that it was only a count down before they lost everything? People would revolt and lose it. Especially after their ancestors were conditioned with the Bible to tolerate and support colonial expansion.
I remember the followers asking when do the decendants of Jacob get to rule, so that was always the expectation. The confusion came from Paul's gentile teachings, where he taught them salvation has come to them, the issue here was that probably should more accurately been translated as welfare, not salvation. Through the fall of Israel the gentiles were able to plunder and get gold from the temple and boost up their finances and status for a longer period of time. I'm still studying this to see if this the case in other documents.
