In Abrahamic religions, a messiah or messias is a saviour or liberator of a group of people. The concepts of moshiach, messianism, and of a Messianic Age originated in Judaism, and in the Hebrew Bible; a moshiach (messiah) is a king or High Priest traditionally anointed with holy anointing oil. Messiahs were not exclusively Jewish: the Book of Isaiah refers to Cyrus the Great, king of the Achaemenid Empire, as a messiah for his decree to rebuild the Jerusalem Temple.
