Mark 9:5-9

5Peter 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.)

7Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”

8Suddenly, when they looked around, they no longer saw anyone with them except Jesus. 9As 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.
