In Moses 7:4 we read:
And I saw the Lord; and he stood before my face, and he talked with me, even as a man talketh one with another, face to face; and he said unto me: Look, and I will show unto thee the world for the space of many generations.
This is similar to 3 Enoch 45 which says:
And I saw Adam and his generation, their deeds and their thoughts (etc.) . . . And every deed of every generation, whether done or to be done in the time to come, to all generations, till the end of time.
Why are there so many correspondences between the Book of Moses and other accounts of Enoch?
