Luke 9:32-36

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.

But while he was saying this, a cloud formed and began to overshadow them; and they were afraid as they entered the cloud.

And then a voice came from the cloud, saying, “This is My Son, My Chosen One; listen to Him!”

And when the voice had spoken, Jesus was found alone. And they kept silent, and reported to no one in those days any of the things which they had seen.
