Mark 9:11-13

11And they asked him, saying, Why say the scribes that Elijah must first come? 12And he answered and told them, Elijah verily cometh first, and restoreth all things; and how it is written of the Son of man, that he must suffer many things, and be set at nought. 13But I say unto you, That Elijah is indeed come, and they have done unto him whatsoever they listed, as it is written of him.
