Matthew 17:13

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

11 And Jesus answered and said unto them, Elias truly shall first come, and restore all things.

12 But I say unto you, That Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them.

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

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

15 Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.

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