Book of Enoch/Chapter 40
CHAPTER XL. 1. And after that I saw thousands of thousands and ten thousand times ten thousand, I saw a multitude beyond number and reckoning, who stood before the Lord of Spirits. 2. And on the four sides of the Lord of Spirits I saw four presences, different from those that sleep not, and I learnt their names: for the angel that went with me made known to me their names, and showed me all the hidden things.
3. And I heard the voices of those four presences as they uttered praises before the Lord of glory. 4. The first voice blesses the Lord of Spirits for ever and ever. 5. And the second voice I heard blessing the Elect One and the elect ones who hang upon the Lord of Spirits. 6. And the third voice I heard pray and intercede for those who dwell on the earth and supplicate in the name of the Lord of Spirits. 7. And I heard the fourth voice fending off the Satans and forbidding them to come before the Lord of Spirits to accuse them who dwell on the earth. 8. After that I asked the angel of peace who went with me, who showed me everything that is hidden: 'Who are these four presences which I have seen and whose words I have heard and written down?' 9. 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.
