Origen

“ But after the dispensation in the mountain, when the disciples were coming down from the mountain in order that, when they had come to the multitude, they might serve the Son of God concerning the salvation of the people, Jesus commanded the disciples saying, “Tell the vision to no man until the Son of man rise from the dead.” ”

“ Wherefore since His being glorified in the resurrection was akin to His transfiguration, and to the vision of His face as the sun, on this account He wishes that these things should then be spoken of by the Apostles, when He rose from the dead. ”
