Jewish traditions holds that the Messiah will come only if there is a Temple for God in Jerusalem. There has not been a Temple in Jerusalem since 70AD when it was torn down by the Romans. The building of the third temple would initiate a period of time where the Messiah is elligible to arise. A key precedent to the prophecy includes the birth of a suitable red heifer without blemish that will serve as a purity ritual to cleanse the nation of Israel.
