Matthew 17:6-9

6And when the disciples heard it, they fell on their face, and were greatly 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, except Jesus only.

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