Luke 9:32-33

Now Peter and those who were with him had been overcome with sleep; but when they were fully awake, they saw His glory and splendor and majesty, and the two men who were standing with Him. And as these [men, Moses and Elijah] were leaving Him, Peter said to Jesus, “Master, it is delightful and good for us to be here; we should make three [sacred] tents; one for You, one for Moses, and one for Elijah”—not realizing what he was saying.
