Art thou elias
And if you are willing to accept [this truth], this person [i.e., John] fulfills [the prophecy of] the coming of Elijah. [See Mal. 4:5-6]
His disciples asked Him, "Why then [since you are obviously the Messiah] do the experts in the law of Moses say that Elijah must come first, [i.e., before the Messiah]?"
He will go on ahead of the Messiah [See verse 76], in the spirit and power of Elijah, to rekindle the affections of fathers for their children, and [to influence] disobedient people to live wisely like righteous people. And he will prepare the people to be ready for [the coming of] the Lord."
Art thou that
They asked him, "Why do you immerse people then, if you are not the Christ, or Elijah, or the prophet [Moses]?"

Why did you go out [to the desert]? To see a prophet? Yes, I should say [he was], and much more than a prophet.
They replied, "Some say you are John the Immerser; some [the prophet] Elijah; and others [the prophet] Jeremiah, or one of the [other] prophets [come back to life]."
some [were saying] that [the prophet] Elijah had appeared; and [still] others [were saying] that one of the [other] prophets of old had risen again [from the dead].
