In our Bibles the last book of the Old testament is that of Malachi. The last verse in the Old Testament and in his book states:
“Lo, I will send you Elijah the prophet, Before the day of the Lord comes, the great and terrible day.”
Being aware of that prophecy, the Scribes were saying that Jesus could not be the Messiah, since Elijah had not come again.
Jesus said that Elijah had already come in the person of John the Baptist.
The story in Chapter Two of the Second Book of Kings describes how whirlwind enveloped Elijah, carrying him off to heaven in a fiery chariot.
The Bible is a poetic book, and the writers often use “Poetic License” to stir up images that ae not factual.
