Luke 9:35

And it came to pass, as they departed from him, Peter said unto Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elias: not knowing what he said.

While he thus spake, there came a cloud, and overshadowed them: and they feared as they entered into the cloud.

And when the voice was past, Jesus was found alone. And they kept it close, and told no man in those days any of those things which they had seen.

And it came to pass, that on the next day, when they were come down from the hill, much people met him.
