Mark 9:11-13

11 And they asked him, saying, Why say the scribes that Elias must first come?

12 And he answered and told them, Elias 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.

13 But I say unto you, That Elias is indeed come, and they have done unto him whatsoever they listed, as it is written of him.
