1 Enoch 39:16
13 And before Him there is no ceasing. He knows before the world was created what is forever and what will be from generation to generation. 14 Those who never sleep bless You: they stand before your glory and bless, praise, and extol, saying: "Holy, holy, holy, is the Lord of Spirits: He fills the earth with spirits."' 15 And here my eyes saw all those who never sleep: they stand before Him and bless and say: 'You are blessed, and blessed be the name of the Lord forever and ever.' 16 And my face was changed; for I could no longer behold.
Luke 9:29
27 But I tell you most certainly, there are some standing here who will not experience death before they see the kingdom of God.” 28 Now about eight days after these sayings, Jesus took with him Peter, John, and James, and went up the mountain to pray. 29 As he was praying, the appearance of his face was transformed, and his clothes became very bright, a brilliant white. 30 Then two men, Moses and Elijah, began talking with him. 31 They appeared in glorious splendor and spoke about his departure that he was about to carry out at Jerusalem.
Notes and References
"... is this a transitional verse: Enoch's face must be transfigured into that of an angel in order fo rhim to see the glory of God, which is surrounded by the myriads of angels (40:1), and the four archangels that flank the divine glory (40:2). For Enoch's transformation into an angel, see 2 Enoch 22. For a parallel to the language here, see Luke's account of Jesus' transfiguration (9:29), which revise Mark's 'he was transfigured' to 'the appearance of his face was different' ..."
