If you are willing to accept it, he is Elijah who is to come.

They said, "Some say John the Baptist, others Elijah, and still others Jeremiah or one of the prophets."

Suddenly, Moses and Elijah appeared to them, talking with Jesus.

Then Peter told Jesus, "Lord, it's good that we're here! If you want, I'll set up three shelters one for you, one for Moses, and one for Elijah."

So the disciples asked him, "Why, then, do the scribes say that Elijah must come first?"

He answered them, "Elijah is indeed coming and will restore all things.

But I tell you that Elijah has already come, yet people did not recognize him and treated him just as they pleased. In the same way, the Son of Man is going to suffer at their hands."

When some of the people standing there heard this, they said, "He's calling for Elijah."

But the others kept saying, "Wait! Let's see if Elijah will come and save him."
