Matthew 17:9
And as they were coming down the mountain, Jesus commanded them: tell no one the vision, until the Son of Man is raised from the dead. The descent brings the command to silence about the vision: tell no one until the Son of Man is raised from the dead. The transfiguration's glory makes sense only in the context of the resurrection — the suffering Christ who was transfigured will be raised from the dead, and then the vision can be shared as testimony to who he was. The resurrection is the context that makes the transfiguration interpretable.
