Mark 9:1-3

1Then Jesus said to them, “Truly I tell you, there are some standing here who will not taste death before they see the kingdom of God arrive with power.”

2After six days Jesus took with Him Peter, James, and John, and led them up a high mountain by themselves. There He was transfigured before them. 3His clothes became radiantly white, brighter than any launderer on earth could bleach them.
