Book of Enoch (1 Enoch) 14:10
And I went into the tongues of fire and drew nigh to a large house which was built of crystals: and the walls of the house were like a tesselated floor (made) of crystals, and its groundwork was of crystal.
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.
