In Moses 7:13 we read that Enoch’s enemies did not repent but instead came to battle against him and lost:
And so great was the faith of Enoch that he led the people of God, and their enemies came to battle against them; and he spake the word of the Lord, and the earth trembled, and the mountains fled, even according to his command; and the rivers of water were turned out of their course; and the roar of the lions was heard out of the wilderness; and all nations feared greatly, so powerful was the word of Enoch, and so great was the power of the language which God had given him.
This resembles the Book of Giants in which the leader of the gibborim describes his defeat in battle:
[… I am a] [mighty warrior], and by the mighty strength of my arm and my own great strength [I went up against a]ll mortals, and I have made war against them; but I am not … able to stand against them.
Surely all these correspondences are not a coincidence? Where would Joseph Smith have learned so much about the story of Enoch?
