Moses 7:56 reads:
And he heard a loud voice; and the heavens were veiled; and all the creations of God mourned; and the earth groaned; and the rocks were rent; and the saints arose, and were crowned at the right hand of the Son of Man, with crowns of glory;
This echoes 3 Enoch 44:7 which reads:
I saw the souls of the fathers of the world, Abraham, Isaac, and Jacob, and the rest of the righteous, who had been raised from their graves and had ascended to heaven.
Where would Joseph Smith have learned this about Enoch?
