Mark 9:2-9 NLT

2 Six days later Jesus took Peter, James, and John to the top of a mountain. No one else was there. As the men watched, Jesus' appearance changed,
3 and his clothing became dazzling white, far whiter than any earthly process could ever make it.
4 Then Elijah and Moses appeared and began talking with Jesus.
5 "Teacher, this is wonderful!" Peter exclaimed. "We will make three shrines a -- one for you, one for Moses, and one for Elijah."
