In Abrahamic religions, the Messiah (Hebrew: מָשִׁיחַ, translit. māšîaḥ, sometimes spelled Moshiach), is the one chosen to lead the world and thereby save it. The term also appears in the forms Messias (Ancient Greek: Μεσσίας), Christ (Ancient Greek: Χριστός), or Al-Masih (Arabic: المسيح, ISO 233: al-masīḥ).
The concepts of the Messiah, Messianism, and the Messianic Age grew from Isaiah's writings (4:2 and chapter 11) during the latter half of the 8th century BCE. The term comes from the Hebrew verb meaning "to apply oil to," to anoint. In the Hebrew Bible, Israel's kings were sometimes called God's "messiah"—God's anointed one. A messiah could also be an anointed high priest or prophet. Messiahs did not even need to descend from Jacob, as the Hebrew Bible refers to Cyrus the Great, king of Persia, as a messiah for his decree to rebuild the Jerusalem Temple.
