Mark 9:1-3

1And he said to them, “I tell you the truth, there are some standing here who will not experience death before they see the kingdom of God come with power.”

2Six days later Jesus took with him Peter, James, and John and led them alone up a high mountain privately. And he was transfigured before them,

3and his clothes became radiantly white, more so than any launderer in the world could bleach them.
