Matthew 17:1-20

1And after six days Jesus takes with [him] Peter, and James, and John his brother, and brings them up into a high mountain apart.

2And he was transfigured before them. And his face shone as the sun, and his garments became white as the light;

3and lo, Moses and Elias appeared to them talking with him.

4And Peter answering said to Jesus, Lord, it is good we should be here. If thou wilt, let us make here three tabernacles: for thee one, and for Moses one, and one for Elias.

5While he was still speaking, behold, a bright cloud overshadowed them, and lo, a voice out of the cloud, saying, This is my beloved Son, in whom I have found my delight: hear him.

6And the disciples hearing [it] fell upon their faces, and were greatly terrified.

7And Jesus coming to [them] touched them, and said, Rise up, and be not terrified.

8And lifting up their eyes, they saw no one but Jesus alone.

9And as they descended from the mountain, Jesus charged them, saying, Tell the vision to no one, until the Son of man be risen up from among [the] dead.

10And [his] disciples demanded of him saying, Why then say the scribes that Elias must first have come?

11And he answering said to them, Elias indeed comes first and will restore all things.

12But 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.

13Then the disciples understood that he spoke to them of John the baptist.

14And when they came to the crowd, a man came to him, falling on his knees before him, and saying,

15Lord, have mercy on my son, for he is lunatic, and suffers sorely; for often he falls into the fire and often into the water.

16And I brought him to thy disciples, and they were not able to heal him.

17And 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.

18And Jesus rebuked him, and the demon went out from him, and the boy was healed from that hour.

19Then the disciples, coming to Jesus apart, said [to him], Why were not we able to cast him out?

20And 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.
