While the final mention of Elijah in the Hebrew Bible is in the Book of Chronicles , the Christian Bible's ordering of the books of the Septuagint places the Book of Malachi , which prophesies a messiah, before the Gospels  and means that Elijah's final Old Testament appearance is in the Book of Malachi , where it is written, "Lo, I will send you the prophet Elijah before the great and terrible day of the Lord comes."  That day is described as the burning of a great furnace, "... so that it will leave them neither root nor branch."  In Christianity it is traditionally believed that Elijah's appearance during the transfiguration of Jesus fulfilled this prophecy. Moreover, in the Gospel of Matthew, Jesus identifies John the Baptist as the spiritual successor to Elijah: "and if you are willing to accept it, he is Elijah who is to come."  Finally, the verses in Malachi are believed to indicate that Elijah has a role in the end-times, immediately before the second coming of Jesus.
