Matthew 17:2-9

2and he was transfigured before them; and his face did shine as the sun, and his garments became white as the light. 3And behold, there appeared unto them Moses and Elijah talking with him. 4And Peter answered, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, I will make here three tabernacles; one for thee, and one for Moses, and one for Elijah. 5While he was yet speaking, behold, a bright cloud overshadowed them: and behold, a voice out of the cloud, saying, This is my beloved Son, in whom I am well pleased; hear ye him. 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 lifting up their eyes, they saw no one, save Jesus only.

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