Luke 9:31-35

They appeared in heavenly glory, talking about his departure which he would soon bring about in Jerusalem. Peter and the others were very sleepy, but when they awoke fully, they saw the glory of Jesus and the two men standing with him. When Moses and Elijah were about to leave, Peter said to Jesus, “Master, it is good that we are here. Let us make three tents—one for you, one for Moses, and one for Elijah.” (Peter did not know what he was talking about.) While he was saying these things, a cloud came and covered them, and they became afraid as the cloud covered them. A voice came from the cloud, saying, “This is my Son, whom I have chosen. Listen to him!”
