Very important passage, the vision of Enoch of the great flood and of the first humans descending from Ham, Shem and Japheth. We see that Noah (the bull) was white and Ham, black, Shem, red, and Japheth, white. The hu(e)mans are from very white (what is called nowadays Albino) to a very dark hue of skin color.
1. And one of those four went to that white bull and instructed him in a secret, without his being terrified: he was born a bull and became a man, and built for himself a great vessel and dwelt thereon; and three bulls dwelt with him in that vessel and they were covered in.
2. And again I raised mine eyes towards heaven and saw a lofty roof, with seven water torrents thereon, and those torrents flowed with much water into an enclosure.
3. And I saw again, and behold fountains were opened on the surface of that great enclosure, and that water began to swell and rise upon the surface, and I saw that enclosure till all its surface was covered with water.
4. And the water, the darkness, and mist increased upon it; and as I looked at the height of that water, that water had risen above the height of that enclosure, and was streaming over that enclosure, and it stood upon the earth.
5. And all the cattle of that enclosure were gathered together until I saw how they sank and were swallowed up and perished in that water.
6. But that vessel floated on the water, while all the oxen and elephants and camels and asses sank to the bottom with all the animals, so that I could no longer see them, and they were not able to escape, (but) perished and sank into the depths.
7. And again I saw in the vision till those water torrents were removed from that high roof, and the chasms of the earth were leveled up and other abysses were opened.
8. Then the water began to run down into these, till the earth became visible; but that vessel settled on the earth, and the darkness retired and light appeared.
9. But that white bull which had become a man came out of that vessel, and the three bulls with him, and one of those three was white like that bull, and one of them was red as blood, and one black: and that white bull departed from them.
You have to read the rest of that vision because we have our own record unfolding from that vision: Joseph, Moshe, YashaYah, John The Baptist and more...
