What Is the Jewish Belief About Moshiach (Messiah)?
What is the “End of Days”?
The term “End of Days” is taken from Numbers 24:14. This has always been taken as a reference to the messianic era. Here we shall explore—albeit briefly—the Jewish belief in the coming of Moshiach (Messiah).
What does the word Moshiach mean?
Moshiach is the Hebrew word for “messiah.” The word messiah in English means a savior or a “hoped-for deliverer.” The word moshiach in Hebrew actually means “anointed.” In Biblical Hebrew, the title moshiach was bestowed on somebody who had attained a position of nobility and greatness. For example, the high priest is referred to as the kohen ha-moshiach.
In Talmudic literature the title Moshiach, or Melech HaMoshiach (the King Messiah), is reserved for the Jewish leader who will redeem Israel in the End of Days.
What is the belief in Moshiach?
One of the principles of Jewish faith enumerated by Maimonides is that one day there will arise a dynamic Jewish leader, a direct descendant of the Davidic dynasty, who will rebuild the Temple in Jerusalem, and gather Jews from all over the world and bring them back to the Land of Israel.
All the nations of the world will recognize Moshiach to be a world leader, and will accept his dominion. In the messianic era there will be world peace, no more wars nor famine, and, in general, a high standard of living.
All mankind will worship one G‑d, and live a more spiritual and moral way of life. The Jewish nation will be preoccupied with learning Torah and fathoming its secrets.
The coming of Moshiach will complete G‑d’s purpose in creation: for man to make an abode for G‑d in the lower worlds—that is, to reveal the inherent spirituality in the material world.
