Luke 9:30-33

³⁰And behold, there talked with him two men, who were Moses and Elijah.

³¹Who appeared in glory, and spoke of his decease which he should accomplish at Jerusalem.

³²But Peter and they that were with him were heavy with sleep: and when they were awake, they saw his glory, and the two men that stood with him.

³³And it came to pass, as they departed from him, Peter said to Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elijah: not knowing what he said.
