Luke 9:32-36

32Meanwhile Peter and his companions were overcome by sleep, but when they awoke, they saw Jesus’ glory and the two men standing with Him. 33As Moses and Elijah were leaving, Peter said to Jesus, “Master, it is good for us to be here. Let us put up three shelters1—one for You, one for Moses, and one for Elijah.” (He did not know what he was saying.)

34While Peter was speaking, a cloud appeared and enveloped them, and they were afraid as they entered the cloud. 35And a voice came from the cloud, saying, “This is My Son, whom I have chosen.2 Listen to Him!”

36After the voice had spoken, only Jesus was present with them. The disciples kept this to themselves, and in those days they did not tell anyone what they had seen.
