Moses 5

Just a thought. First -

"...Cain was shut out from the presence of the Lord, and with his wife and many of his brethren dwelt in the land of Nod, on the east of Eden."  (Moses 5:41)

And -

"...from the days of Cain, there was a secret combination, and their works were in the dark, and they knew every man his brother.
52 Wherefore the Lord cursed Lamech, and his house, and all them that had covenanted with Satan; for they kept not the commandments of God, and it displeased God, and he ministered not unto them, and their works were abominations, and began to spread among all the sons of men. And it was among the sons of men."  (Moses 5:51–52)

Sounds like the sons of men today.
