After six days Jesus took with him Peter and James and John, and led them up a high mountain apart by themselves; and he was transfigured before them,æand his garments became glistening, intensely white, as no fuller on earth could bleach them. And there appeared to them Elijah with Moses; and they were talking to Jesus.
And Peter said to Jesus, "Master, it is well that we are here; let us make three booths, one for you and one for Moses and one for Elijah." For he did not know what to say, for they were exceedingly afraid.
And a cloud overshadowed them, and a voice came out of the cloud, "This is my beloved Son; listen to him." — Mark 9:2-7 (RSV)
