Mark 9:2-9

After six days Jesus took only Peter, James, and John and led them up a high mountain where they could be alone. Jesus’ appearance changed in front of them. His clothes became dazzling white, whiter than anyone on earth could bleach them. Then Elijah and Moses appeared to them and were talking with Jesus. Peter said to Jesus, “Rabbi, it’s good that we’re here. Let’s put up three tents—one for you, one for Moses, and one for Elijah.” (Peter didn’t know how to respond. He and the others were terrified.) Then a cloud overshadowed them. A voice came out of the cloud and said, “This is my Son, whom I love. Listen to him!” Suddenly, as they looked around, they saw no one with them but Jesus. On their way down the mountain, Jesus ordered them not to tell anyone what they had seen. They were to wait until the Son of Man had come back to life.
