Mark 9:2-12

2 Six days later, Jesus took with Him Peter, James, and John, and brought them alone, apart from the rest, up a high mountain; and in their presence His appearance underwent a change.

3 His garments also became dazzling with brilliant whiteness--such whiteness as no bleaching on earth could give.

4 Moreover there appeared to them Elijah accompanied by Moses; and the two were conversing with Jesus,

5 when Peter said to Jesus, "Rabbi, we are thankful to you that we are here. Let us put up three tents--one for you, one for Moses, and one for Elijah."

6 For he knew not what to say: they were filled with such awe.

7 Then there came a cloud spreading over them, and a voice issued from the cloud, "This is my Son, dearly loved: listen to Him."

8 Instantly they looked round, and now they could no longer see any one, but themselves and Jesus.

9 As they were coming down from the mountain, He very strictly forbad them to tell any one what they had seen "until after the Son of Man has risen from among the dead."

10 So they kept the matter to themselves, although frequently asking one another what was meant by the rising from the dead.

11 They also asked Him, "How is it that the Scribes say that Elijah must first come?"

12 "Elijah," He replied, "does indeed come first and reforms everything; but how is it that it is written of the Son of Man that He will endure much suffering and be held in contempt?
