Enoch - And he said to me: 'This first is Michael, the merciful and long-suffering: and the second, who is set over all the diseases and all the wounds of the children of men, is Raphael: and the third, who is set over all the powers, is Gabriel: and the fourth, who is set over the repentance unto hope of those who inherit eternal life, is named Phanuel.' And these are the four angels of the Lord of Spirits and the four voices I heard in those days.

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.
