Book of Enoch (1 Enoch) 67:3
And I will make fast thy seed before me for ever and ever, and I will spread abroad those who dwell with thee: it shall not be unfruitful on the face of the earth, but it shall be blessed and multiply on the earth in the name of the Lord.’
Background and history of Book of Enoch (1 Enoch), and issues with this book.
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.
