The Transfiguration appears in the Gospels of Matthew, Mark and Luke. Matthew’s version is the most complete:
1Six days later, Jesus took with him Peter and James and his brother John and led them up a high mountain, by themselves. 2And he was transfigured before them, and his face shone like the sun, and his clothes became dazzling white. 3Suddenly there appeared to them Moses and Elijah, talking with him. 4Then Peter said to Jesus, “Lord, it is good for us to be here; if you wish, I will make three tents here, one for you, one for Moses, and one for Elijah.” 5While he was still speaking, suddenly a bright cloud overshadowed them, and from the cloud a voice said, “This is my beloved Son, with whom I am well pleased; listen to him!” 6When the disciples heard this, they fell to the ground and were overcome by fear. 7But Jesus came and touched them, saying, “Get up and do not be afraid.” 8And when they looked up, they saw no one except Jesus himself alone.
