Mark 9:15

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.

14 And when he came to [his] disciples, he saw a great multitude about them, and the scribes questioning with them.

15 And straightway all the people, when they beheld him, were greatly amazed, and running to [him] saluted him.

16 And he asked the scribes, What question ye with them?

17 And one of the multitude answered and said, Master, I have brought unto thee my son, which hath a dumb spirit;

18 And wheresoever he taketh him, he teareth him: and he foameth, and gnasheth with his teeth, and pineth away: and I spake to thy disciples that they should cast him out; and they could not.
