Book of Enoch (1 Enoch) 82:1

And now, my son Methuselah, all these things I am recounting to thee and writing down for thee, and I have revealed to thee everything, and given thee books concerning all these: so preserve, my son Methuselah, the books from thy father’s hand, and (see) that thou deliver them to the generations of the world.

R. H. Charles, The Book of Enoch (London: SPCK, 1917), public domain. The verse text is the English Wikisource transcription of that translation. Charles’s editorial signs are kept. He rearranges some verses in chapters 5, 39, 90, 91, and 106, so those chapters are not a straight 1, 2, 3 sequence.
