Luke 9:28-32

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

29And as he prayed the fashion of his countenance became different and his raiment white [and] effulgent.

30And lo, two men talked with him, who were Moses and Elias,

31who, appearing in glory, spoke of his departure which he was about to accomplish in Jerusalem.

32But Peter and those with him were oppressed with sleep: but having fully awoke up they saw his glory, and the two men who stood with him.
