A lot of Rabbis in the Talmud grappled with this problem and created an arbitrary distinction that if the Jews behaved well he would come in glory and that if they behaved poorly he would come lowly but there is no Biblical evidence to support this. According to Daniel, there were certain prophecies that had to be fulfilled before the year 70 CE and before the destruction of the Second Temple (such as the coming of the Messiah). Some believe this means that if Jesus did not fulfill the Messianic prophecies, there is no other candidate.
