The disciples asked Jesus, "Don't the teachers of the Law of Moses say that Elijah must come before the Messiah does?"
I, the LORD All-Powerful, will send my messenger to prepare the way for me. Then suddenly the Lord you are looking for will appear in his temple. The messenger you desire is coming with my promise, and he is on his way.
I, the LORD, promise to send the prophet Elijah before that great and terrible day comes.
And if you believe them, John is Elijah, the prophet you are waiting for.
So they kept it to themselves. But they wondered what he meant by the words "raised from death."
Then Moses and Elijah were there talking with Jesus.
