Matthew 17:1-9 Revised Standard Version Catholic Edition (RSVCE)
17 And after six days Jesus took with him Peter and James and John his brother, and led them up a high mountain apart. 2 And he was transfigured before them, and his face shone like the sun, and his garments became white as light. 3 And behold, there appeared to them Moses and Eli′jah, talking with him. 4 And Peter said to Jesus, “Lord, it is well that we are here; if you wish, I will make three booths here, one for you and one for Moses and one for Eli′jah.”[a] 5 He was still speaking, when lo, a bright cloud overshadowed them, and a voice from the cloud said, “This is my beloved Son,[b] with whom I am well pleased; listen to him.” 6 When the disciples heard this, they fell on their faces, and were filled with awe. 7 But Jesus came and touched them, saying, “Rise, and have no fear.” 8 And when they lifted up their eyes, they saw no one but Jesus only.
9 And as they were coming down the mountain, Jesus commanded them, “Tell no one the vision, until the Son of man is raised from the dead.”
