At that time, Jesus taketh unto him Peter and James, and John his brother, and bringeth them up into a high mountain apart: And he was transfigured before them. And his face did shine as the sun: and his garments became white as snow. And behold there appeared to them Moses and Elias talking with him. And Peter answering, said to Jesus: “Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles, one for thee, and one for Moses, and one for Elias.”
And as he was yet speaking, behold a bright cloud overshadowed them. And lo a voice out of the cloud, saying: “This is my beloved Son, in whom I am well pleased: hear ye him.” And the disciples hearing fell upon their face, and were very much afraid. And Jesus came and touched them: and said to them: “Arise, and fear not.” And they lifting up their eyes, saw no one, but only Jesus. And as they came down from the mountain, Jesus charged them, saying: “Tell the vision to no man, till the Son of man be risen from the dead.” Matthew 17:1-19
