Matthew 17:6-9

6And when the disciples heard it, they fell on their face, and were sore afraid.

7And Jesus came and touched them, and said, Arise, and be not afraid.

8And when they had lifted up their eyes, they saw no man, save Jesus only.

9And as they came down from the mountain, Jesus charged them, saying, Tell the vision to no man, until the Son of man be risen again from the dead.
