Bhairitu, For the Hassidic and conservative Jews, the messiah is a very specific expectation that they believe is written in the Torah. For example, they expect their messiah to be a political leader who would restore the glory of the kingdom of David and Solomon. For this reason, the Jews today and yesteryear reject the teachings of Jesus.
IMO, this same expectation is causing the political unrest in the Middle East today. Specifically, the Israelis have created an apartheid government in Palestine against the people who rightfully own the land that the Israelis are occupying.
