The “messiah” is supposed to be great political and military leader.
He also is supposed to make all Jews return to Israel,and make it the centre of the world government, with Jewish law as the basis for the entire world.
All other world religions will cease to exist as all humans will recognise the Jewish God as the one true God, and the Jewish religion as the only true religion.
And then of course he is supposed to start the “messianic age” were war, hatred and violence cease to exist. Even carnivore animals are supposed to become vegetarian.
And to top it all off, the Messiah is supposed to be fully human, not a demigod, not a son of god, and he is supposed to achieve all of the above in one lifetime.
No “second coming.”
You can see why Jews reject Jesus as the Messiah.
He did not fulfill any of the criteria.
