Book of Enoch (1 Enoch) 94:5
And hold fast my words in the thoughts of your hearts, And suffer them not to be effaced from your hearts; For I know that sinners will tempt men to evilly-entreat wisdom, So that no place may be found for her, And no manner of temptation may minish.
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.
