1 Enoch 9:1
1 And then Michael, Uriel, Raphael, and Gabriel looked down from heaven and saw much blood being shed on the earth, and all lawlessness being committed on the earth. 2 And they said to one another: 'The earth, left without inhabitants, cries out, and the voice of their crying reaches the gates of heaven.' 3 'And now to you, the holy ones of heaven, the souls of men plead, saying, "Present our case before the Most High."'
1QM 9
The War ScrollThe tower shall advance from the formation and shall have one hundred shields to each side; in this [manner,] the tower shall be surrounded on three sides by three hundred shields. And it shall also have two gates, one to the right and one to the left. They shall write on all the shields of the towers: on the first, Michael, on the second, Gabriel, on the third, Sariel, and on the fourth, Raphael. Michael and Gabriel shall stand on the right, and Sariel and Raphael on the left ... they shall set an ambush to... our camps and to keep us from all that is indecent and evil.
Notes and References
"... A complement of four, and later seven, named archangels (here “holy ones”) appears first in 1 Enoch 9–10 and then becomes something of a staple in Jewish and Christian literature. Their existence and the number four were doubtless inferred from the four living creatures in the throne vision of Ezekiel 1–2, and they are implicit in Zechariah 1. The later literature makes an association with Ezekiel 1–2 explicit. In the action of 1 Enoch 9–10, however, the four are not placed at the throne. They go forth from heaven, view the world, approach the divine throne with their petition in behalf of humanity, and are then dispatched to the world to act in God’s behalf ... The four angels are mentioned in the Qumran War Scroll, remarkably with the same names as here, in the order Michael, Gabriel, Sariel, and Raphael (1QM 9). Their association with the eschatological war is compatible with the activity of Raphael, Gabriel, and Michael in 1 Enoch 10 ..."
