Luke 9:29 In-Context

27 But truly I tell you, there are some standing here who will not taste death before they see the kingdom of God."
28 Now about eight days after these sayings Jesus took with him Peter and John and James, and went up on the mountain to pray.
29 And while he was praying, the appearance of his face changed, and his clothes became dazzling white.
30 Suddenly they saw two men, Moses and Elijah, talking to him.
31 They appeared in glory and were speaking of his departure, which he was about to accomplish at Jerusalem.
