The Trend of Jewish Thought
It was under these very circumstances that Jesus appeared, proclaiming himself as the Messiah. He told the Jewish people that he was the Son of God-the very people who thought that he was simply a man from Nazareth. They had not yet heard any news of Elijah's coming" so they asked "how could it be possible that Jesus of Nazareth is the Son of God!"
The Jewish people expect Elijah to return the same way he was taken up by a whirlwind into heaven i.e. same Elijah coming down from heaven in a flaming chariot!
