Lucas 9

27 But I tell you truly, some who are standing here will not taste death before they see the kingdom of God."

The Transfiguration

28 About eight days after Jesus had said these things, He took with Him Peter, John, and James, and went up on a mountain to pray. 29 And as He was praying, the appearance of His face changed, and His clothes became radiantly white. 30 Suddenly two men, Moses and Elijah, began talking with Jesus. 31 They appeared in glory and spoke about His departure, which He was about to accomplish at Jerusalem.
