Mark 9:2-9 (CEB)
2 Six days later Jesus took Peter, James, and John, and brought them to the top of a very high mountain where they were alone. He was transformed in front of them, 3 and his clothes were amazingly bright, brighter than if they had been bleached white. 4 Elijah and Moses appeared and were talking with Jesus. 5 Peter reacted to all of this by saying to Jesus, “Rabbi, it’s good that we’re here. Let’s make three shrines—one for you, one for Moses, and one for Elijah.” 6 He said this because he didn’t know how to respond, for the three of them were terrified.
7 Then a cloud overshadowed them, and a voice spoke from the cloud, “This is my Son, whom I dearly love. Listen to him!” 8 Suddenly, looking around, they no longer saw anyone with them except Jesus.
9 As they were coming down the mountain, he ordered them not to tell anyone what they had seen until after the Human One[a] had risen from the dead.
