The Holy Scripture
2 Baruch
Chapter LIII
And when I had said these things I fell asleep there, and I saw a vision, and lo! a cloud was ascending from a very great sea, and I kept gazing upon it) and lo! it was full of waters white and black, and there were many colors in those self-same waters, and as it were the likeness of great lightning was seen at its summit.
And I saw the cloud passing swiftly in quick courses, and it covered all the earth.
