Luke 9:32-36

32But Peter and those with him were oppressed with sleep: but having fully awoke up they saw his glory, and the two men who stood with him.

33And it came to pass as they departed from him, Peter said to 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.

34But as he was saying these things, there came a cloud and overshadowed them, and they feared as they entered into the cloud:

35and there was a voice out of the cloud saying, This is my beloved Son: hear him.

36And as the voice was [heard] Jesus was found alone: and they kept silence, and told no one in those days any of the things they had seen.
