1 Enoch 46:1
1 And there I saw One who had a head of days, And His head was white like wool, And with Him was another being whose countenance had the appearance of a man, And his face was full of graciousness, like one of the holy angels. 2 And I asked the angel who went with me and showed me all the hidden things, concerning that Son of Man, who he was, and whence he was, (and) why he went with the Head of Days? And he answered and said unto me: This is the son of Man who hath righteousness, With whom dwelleth righteousness, And who revealeth all the treasures of that which is hidden, Because the Lord of Spirits hath chosen him, And whose lot hath the pre-eminence before the Lord of Spirits in uprightness for ever.
Acts 6:15
13 They brought forward false witnesses who said, “This man does not stop saying things against this holy place and the law. 14 For we have heard him saying that Jesus the Nazarene will destroy this place and change the customs that Moses handed down to us.” 15 All who were sitting in the council looked intently at Stephen and saw his face was like the face of an angel.
Notes and References
"... In conclusion, we must again draw our attention to the account of Enoch’s glorified face, as it is found in the first chapter of the Slavonic apocalypse. It is possible that this transformational account was designed by its authors not only to proleptically anticipate the seer’s glorious metamorphosis before the fearful face, but also to anticipate the eschatological transformation of the righteous (Such proleptic glorifications that anticipate the future glorious transformation of the seer can be found in some Jewish and Christian accounts, including the metamorphosis of Stephen in Acts 6:15) ..."
