Isaiah wrote of one of several "anointed" people, for example namely the conqueror Cyrus in Isa 44:28-45:4, called by name by God before he was born, brought to power for the sake of Israel. That deliverer appeared later in Daniel. The Hebrew" "מָשִׁיחַwas translated to Aramaic "māshîaḥ", then Eng "anointed" and "Christ", "Immanuel". The man fulfilled that prophecy in Isaiah. The point is that the word we know as Messiah, as referring to the eternal heavenly Anointed who would establish a perfect society in the end for Israel, is in fact a concept established in the Tanakh, from Genesis onward. There were numerous candidates considered "anointed" saviors, such a David, but also priests, other kings, and non religious people. Two classes of messiahs existed among the Jews, flesh and spiritual. It wasn't until after the Maccabees that Israel suffered so much under the iron heel of Rome that they began hoping for a fleshly anointed savior, (a THE Messiah), a forerunner of the last on the list of Messiahs that would rescue them. God sent Jesus, but they rejected Him, so suffered beyond comprehension for two thousands of years.
The other prophecies related to Christianity, according to inspired knowledge from the Spirit, and historical facts such as from Josephus and other Church Fathers, those prophesies I wrote about above, are only possibly fulfilled line by line by Jesus of Nazarath, God's Anointed for rescue then and on to now and beyond, for he is the only one that remains, having risen from the grave. The last earthly accepted anointed one was the High Priest of Jesus' time, who failed as subordinate acting king of the Jews, out-performed by the Roman appointed king Herod. From then on a few activists resisting Rome were hoped to be messiahs until Israel was dispersed. upon the siege of Jerusalem in 70AD
