Luke 9:33-35

33As the men were leaving Jesus, Peter said to him, “Master, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” (He did not know what he was saying.) 34While he was speaking, a cloud appeared and covered them, and they were afraid as they entered the cloud. 35A voice came from the cloud, saying, “This is my Son, whom I have chosen; listen to him.”
