Mark 9:4-8

And Elijah appeared to them with Moses, and they were talking with Jesus. Then Peter answered and said to Jesus, “Rabbi, it is good for us to be here; and let us make three tabernacles: one for You, one for Moses, and one for Elijah”— because he did not know what to say, for they were greatly afraid. And a cloud came and overshadowed them; and a voice came out of the cloud, saying, “This is My beloved Son. Hear Him!” Suddenly, when they had looked around, they saw no one anymore, but only Jesus with themselves.
