Luke 9:28-33

Some eight days after these sayings, He took along Peter and John and James, and went up on the mountain to pray. And while He was praying, the appearance of His face became different, and His clothing became white and gleaming. And behold, two men were talking with Him; and they were Moses and Elijah, who, appearing in glory, were speaking of His departure which He was about to accomplish at Jerusalem. Now Peter and his companions had been overcome with sleep; but when they were fully awake, they saw His glory and the two men standing with Him. And as these were leaving Him, Peter said to Jesus, “Master, it is good for us to be here; let us make three tabernacles: one for You, and one for Moses, and one for Elijah”—not realizing what he was saying.
