In Moses 7:26 we read
And he beheld Satan; and he had a great chain in his hand, and it veiled the whole face of the earth with darkness; and he looked up and laughed, and his angels rejoiced.
This echoes 1 Enoch 53:3-4 which reads
So I saw all the angels of plague cooperating and preparing all the chains of Satan. And I asked the angel of peace, who was going with me, For whom are they preparing these chains?
Why is there such a correspondence between the Book of Moses and other accounts of Enoch?
