10. And his disciples demanded of him saying, Why then say the scribes that Elias must first have come?
11. And he answering said to them, Elias indeed comes first and will restore all things.
12. But I say unto you that Elias has already come, and they have not known him, but have done unto him whatever they would. Thus also the Son of man is about to suffer from them.
13. Then the disciples understood that he spoke to them of John the baptist.
14. And when they came to the crowd, a man came to him, falling on his knees before him, and saying,
15. Lord, have mercy on my son, for he is lunatic, and suffers sorely; for often he falls into the fire and often into the water.
16. And I brought him to thy disciples, and they were not able to heal him.
17. And Jesus answering said, O unbelieving and perverted generation, how long shall I be with you? how long shall I bear with you? Bring him here to me.
18. And Jesus rebuked him, and the demon went out from him, and the boy was healed from that hour.
19. Then the disciples, coming to Jesus apart, said to him, Why were not we able to cast him out?
20. And he says to them, Because of your unbelief; for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say to this mountain, Be transported hence there, and it shall transport itself; and nothing shall be impossible to you.
21. But this kind does not go out but by prayer and fasting.
