34 While he was speaking, a cloud appeared and covered them, and they were afraid as they entered the cloud.
35 A voice came from the cloud, saying, “This is my Son, whom I have chosen; listen to him.”
36 When the voice had spoken, they found that Jesus was alone. The disciples kept this to themselves and did not tell anyone at that time what they had seen.
