Six days later, Jesus took with him Peter and James and his brother John and led them up a high mountain, by themselves.
And he was transfigured before them, and his face shone like the sun, and his clothes became dazzling white.
Suddenly there appeared to them Moses and Elijah, talking with him.
Then Peter said to Jesus, "Lord, it is good for us to be here; if you wish, I will make three dwellings here, one for you, one for Moses, and one for Elijah."
