Luke 9:30

28About eight days after these sayings, he took with him Peter, John, and James, and went up onto the mountain to pray.

29As he was praying, the appearance of his face was altered, and his clothing became white and dazzling.

30Behold, two men were talking with him, who were Moses and Elijah,

31who appeared in glory and spoke of his departure, which he was about to accomplish at Jerusalem.

32Now Peter and those who were with him were heavy with sleep, but when they were fully awake, they saw his glory, and the two men who stood with him.
