Mark 9:2-8 CSB
After six days Jesus took Peter, James, and John and led them up a high mountain by themselves to be alone. He was transfigured in front of them, and his clothes became dazzling — extremely white as no launderer on earth could whiten them. Elijah appeared to them with Moses, and they were talking with Jesus. Peter said to Jesus, “Rabbi, it’s good for us to be here. Let’s set up three shelters: one for you, one for Moses, and one for Elijah” — because he did not know what to say, since they were terrified. A cloud appeared, overshadowing them, and a voice came from the cloud: “This is my beloved Son; listen to him!” Suddenly, looking around, they no longer saw anyone with them except Jesus.
