6for he did not know what he should say, for they were terrified.
7And a cloud appeared overshadowing them, and a voice came out of the cloud, saying, “This is My beloved Son. Listen to Him!”
8And suddenly, looking around, they no longer saw anyone, but only Jesus with themselves.
9And as they came down from the mountain, He commanded them that they should relate to no one the things they had seen, till the Son of Man should rise from the dead.
10And this word they kept to themselves, questioning what it meant to rise from the dead.
