Matthew 17:13

10 And his disciples asked him, saying, Why then say the scribes that Elijah must first come?

11 And he answered and said, Elijah indeed cometh, and shall restore all things:

12 but I say into you, that Elijah is come already, and they knew him not, but did unto him whatsoever they would. Even so shall the Son of man also suffer of them.

13 Then understood the disciples that he spake unto them of John the Baptist.

14 And when they were come to the multitude, there came to him a man, kneeling to him, saying,

15 Lord, have mercy on my son: for he is epileptic, and suffereth grievously; for oft-times he falleth into the fire, and off-times into the water.

16 And I brought him to thy disciples, and they could not cure him.
