 That's really interesting because in Luke's version of the transfiguration, when it talks about this cloud enveloping them, it's the same word that Luke uses for when the Holy Spirit envelopes Mary. We often hear that translated as the Holy Spirit overshadows Mary. Gabriel, during the Annunciation, says the Holy Spirit will overshadow you. But really, it's like it envelopes you. That's the Greek word that is used. Very same word that we see here on the Mount of Transfiguration.
