Matthew 17:6

3 And, behold, there appeared unto them Moses and Elias talking with him.

4 Then answered Peter, and said unto 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.

5 While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him.

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

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

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

9 And 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.
