In Moses 6:41, Enoch says:
I came out from the land of Cainan, the land of my fathers, a land of righteousness unto this day.
Enoch describes his home as a land of righteousness which has parallels with the Book of Giants. The leader of the gibborim in the Book of Giants says that his “opponents…reside in the heavens and live with the holy ones”
Where would Joseph Smith have gotten this information from?
