Lucas 9

27 I tell you the truth, some standing here right now will not die before they see the Kingdom of God."

The Transfiguration

28 About eight days later Jesus took Peter, John, and James up on a mountain to pray. 29 And as he was praying, the appearance of his face was transformed, and his clothes became dazzling white. 30 Suddenly, two men, Moses and Elijah, appeared and began talking with Jesus. 31 They were glorious to see. And they were speaking about his exodus from this world, which was about to be fulfilled in Jerusalem.
