Whom did Christ indicate as fulfilling this prophecy?

Answer

"And His disciples asked Him, saying, Why then say the scribes that Elias must first come? And Jesus
answered and said unto them, Elias truly shall first come, and restore all things. But I say unto you, That
Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Like wise
shall also the Son of man suffer of them. Then the disciples understood that He spoke unto them of John
the Baptist." Matt. 17:10-13.
