Luke 9:28-33

²⁸And it came to pass about eight days after these words, that he took Peter, and James, and John, and went up into a mountain to pray.

²⁹And whilst he prayed, the shape of his countenance was altered, and his raiment became white and glittering.

³⁰And behold two men were talking with him. And they were Moses and Elias,

³¹Appearing in majesty. And they spoke of his decease that he should accomplish in Jerusalem.

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

³³And it came to pass, that as they were departing from him, Peter saith 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 Elias; not knowing what he said.
