Mark 9:2-9

² Six days later, Jesus took with him Peter and James and John, and led them up a high mountain apart, by themselves. And he was transfigured before them, ³ and his clothes became dazzling white, such as no one on earth could bleach them. ⁴ And there appeared to them Elijah with Moses, who were talking with Jesus. ⁵ Then Peter said to Jesus, “Rabbi, it is good for us to be here; let us make three dwellings, one for you, one for Moses, and one for Elijah.” ⁶ He did not know what to say, for they were terrified. ⁷ Then a cloud overshadowed them, and from the cloud there came a voice, “This is my Son, the Beloved; listen to him!” ⁸ Suddenly when they looked around, they saw no one with them any more, but only Jesus.

⁹ As they were coming down the mountain, he ordered them to tell no one about what they had seen, until after the Son of Man had risen from the dead.
