The Hebrew word for Messiah is “mashiach,” which means “anointed” or “anointed one.” To be anointed is to be set apart and commissioned by God to carry out His specific will in a specific capacity. In the Tenach, three types of people were anointed—prophets, priests and kings. So in one sense, many different “messiahs” or “anointed ones” appear in biblical Jewish history.
There have also been people outside of the biblical record who have declared themselves to be messiahs sent to save the Jewish people from tyranny and oppression. Yet these proved to be charlatans, and some of them led thousands of Jews to their untimely deaths.
Here is a long list of men who claimed to be the Jewish messiah (or his forerunner) from Wikipedia:
Jewish Messiah Claimants
Simon(ca. 4 BC), a former slave of Herod the Great who rebelled.
Athronges(ca. 3 BC)
Judas of Galilee (?), son of Hezekiah/Ezekias, a member of the Zealots faction who led a bloody revolt against a Roman census in AD 6
Theudas(? - 46), who attempted a short-lived revolt against the Romans before being slain.
"Egyptian Prophet", c.55, with 30,000 unarmed Jews doing The Exodus reenactment massacred by Procurator Antonius Felix (JW2.13.5, JA20.8.6, Acts 21:38)
Menahem ben Judah (?), allegedly son of Judas of Galilee, partook in a revolt against Agrippa II before being slain by a rival Zealot leader.
Vespasian, c.70, according to Josephus
Simon bar Kokhba (?- ca. 135), founded a short-lived Jewish state before being defeated in the Second Jewish-Roman War.
Moses of Crete (?), who in about 440-470 convinced the Jews of Crete to attempt to walk into the sea to return to Israel; he disappeared after that disaster.
Ishak ben Ya'kub Obadiah Abu 'Isa al-Isfahani (684-705), who led a revolt in Persia against the Umayyad Caliph 'Abd al-Malik ibn Marwan.
Yudghan (?), a disciple of Abu 'Isa who continued the faith after Isa was slain.
Serene (?), who around 720 claimed to be the Messiah and advocated expulsion of Muslims and relaxing various rabbinic laws before being arrested; he then recanted.
David Alroy (?), born in Kurdistan, who around 1160 agitated against the caliph before being assassinated.
Nissim ben Abraham (?), active around 1295.
Moses Botarel of Cisneros (?), active around 1413; claimed to be a sorcerer able to combine the names of God.
Asher Lemmlein (?), a German near Venice who proclaimed himself a forerunner of the Messiah in 1502.
David Reubeni (1490-1541?) and Solomon Molcho (1500-1532), adventurers who travelled in Portugal, Italy, and Turkey; Molcho was eventually burned at the stake by the Pope.
Sabbatai Zevi (1626-1676), an Ottoman Jew who claimed to be the Messiah, but then converted to Islam; still has followers today in the Donmeh.
Barukhia Russo (Osman Baba), successor of Sabbatai Zevi.
Jacob Querido (?-1690), claimed to be the new incarnation of Sabbatai; later converted to Islam and led the Donmeh.
Miguel Cardoso (1630-1706), another successor of Sabbatai who claimed to be the "Messiah ben Ephraim."
Mordecai Mokia (1650-1729), "the Rebuker," another person who proclaimed himself Messiah after Sabbatai's death.
Löbele Prossnitz (?-1750), a proven fraud who nevertheless attained some following amongst former followers of Sabbatai, calling himself the "Messiah ben Joseph."
Jacob Joseph Frank (1726-1791), who claimed to be the reincarnation of King David and preached a synthesis of Christianity and Judaism.
Menachem Mendel Schneerson (1902-1994), the seventh Chabad Rabbi who tried to "prepare the way" for the Messiah. Some of his followers believe him to be the Messiah, but this belief is declining.
Did you ever hear a relative say, “When the Messiah comes…?” Perhaps you have read in Jewish literature or seen in films something about this belief in a coming Messiah.
Perhaps you have never even heard mention of a Messiah because recent Judaism has for the most part dismissed the idea or redefined it to mean a golden age of peace and good will brought about by human achievement.
Nevertheless, in the Tenach, from the first book of Genesis to the last prophet, Malachi, there are hundreds of scriptures about a unique Person who is coming to save, to redeem, and to bless, not only Israel, but the entire world.
