Enoch - And that Head of Days came with Michael and Gabriel, Raphael and Phanuel, thousands and ten thousands of angels without number.
[Lost passage wherein the Son of Man was described as accompanying the Head of Days, and Enoch asked one of the angels concerning the Son of Man as to who he was.]

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
