2 After six days Jesus took Peter, James and John with him and led them up a high mountain, where they were all alone. There he was transfigured before them. 3 His clothes became dazzling white, whiter than anyone in the world could bleach them. 4 And there appeared before them Elijah and Moses, who were talking with Jesus.
5 Peter said to Jesus, “Rabbi, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” 6 (He did not know what to say, they were so frightened.)
7 Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”
8 Suddenly, when they looked around, they no longer saw anyone with them except Jesus.
9 As they were coming down the mountain, Jesus gave them orders not to tell anyone what they had seen until the Son of Man had risen from the dead.
2 Peter 1:16-19
16 For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. 17 He received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, “This is my Son, whom I love; with him I am well pleased.”[a] 18 We ourselves heard this voice that came from heaven when we were with him on the sacred mountain.
19 We also have the prophetic message as something completely reliable,and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts.
