Mark 9:2-9New Revised Standard Version (NRSV)
2 Six days later, Jesus took with him Peter and James and John, and led them up a high mountain apart, by themselves. And he was transfigured before them, 3 and his clothes became dazzling white, such as no one[a] on earth could bleach them. 4 And there appeared to them Elijah with Moses, who were talking with Jesus. 5 Then Peter said to Jesus, “Rabbi, it is good for us to be here; let us make three dwellings,[b] one for you, one for Moses, and one for Elijah.” 6 He did not know what to say, for they were terrified. 7 Then a cloud overshadowed them, and from the cloud there came a voice, “This is my Son, the Beloved;[c] listen to him!” 8 Suddenly when they looked around, they saw no one with them any more, but only Jesus.
The Coming of Elijah
9 As they were coming down the mountain, he ordered them to tell no one about what they had seen, until after the Son of Man had risen from the dead.
Mark 9:2-9New International Version (NIV)
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.
