While Jesus was still speaking, suddenly a bright cloud overshadowed them, and from the cloud a voice said, "This is my Son, the Beloved; with him I am well pleased; listen to him!" When the disciples heard this, they fell to the ground and were overcome by fear. But Jesus came and touched them, saying, "Get up and do not be afraid." And when they looked up, they saw no one except Jesus himself alone.

(Matthew 17:5-8)
