Luke 9:28-33

28Now about eight days after these sayings he took with him Peter and John and James and went up on the mountain to pray.

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

30And behold, two men were talking with him, 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 became fully awake they saw his glory and the two men who stood with him.

33And as the men were parting from him, Peter said to Jesus, "Master, it is good that we are here. Let us make three tents, one for you and one for Moses and one for Elijah"—not knowing what he said.
