Luke 9:29-33

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 who were standing with Him.

And as these two men were leaving Him, Peter said to Jesus, “Master, it is good that we are here; and let’s make three tabernacles: one for You, one for Moses, and one for Elijah”—not realizing what he was saying.
