Luke 9:34-36

9:34 As he was saying this, a cloud came and overshadowed them, and they were afraid as they entered the cloud. 9:35 Then a voice came from the cloud, saying, “This is my Son, my Chosen One. Listen to him!” 9:36 After the voice had spoken, Jesus was found alone. So they kept silent and told no one at that time anything of what they had seen.
