Luke 9:33; Luke 9:19

33 As 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.)

19 They replied, “Some say John the Baptist; others say Elijah; and still others, that one of the prophets of long ago has come back to life.”
