28 Now about eight days after these sayings he took with him Peter and John and James and went up on the mountain to pray. 29 And as he was praying, the appearance of his face was altered, and his clothing became dazzling white. 30 And behold, two men were talking with him, Moses and Elijah, 31 who appeared in glory and spoke of his departure, which he was about to accomplish at Jerusalem.
