Luke 9:34-36

While Peter was still speaking, a radiant cloud of glory formed above them and overshadowed them. As the glory cloud enveloped them, they were struck with fear. Then the voice of God thundered from within the cloud, “This is my Son, my Beloved One. Listen carefully to all he has to say.” When the thunderous voice faded away and the cloud disappeared, Jesus was standing there alone. Peter, Jacob, and John were awestruck. But they didn’t say a word to anyone about what they had seen.
