1 Enoch 40:8
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?'
Testament of Benjamin 6:2
Testament of the Twelve PatriarchsThe inclination of the good man is not in the power of the deceit of the spirit of Beliar, for the angel of peace guideth his soul. And he gazeth not passionately upon corruptible things, nor gathereth together riches through a desire of pleasure. He delighteth not in pleasure, [he grieveth for not his neighbour], he sateth not himself with luxuries, he erreth not in the uplifting of the eyes, the Lord is his portion. The good inclination receiveth not glory nor dishonor from men, and it knoweth not any guile, or lie, or fighting or reviling; for the Lord dwelleth in him and lighteth up his soul, and he rejoiceth towards all men alway.
Notes and References
"... Michael has a specific connection to trees and medicine. Thus he teaches agriculture in Vita 22:2; reveals the fruits of the tree to be eaten in the future by the righteous in 1 Enoch 25, and is one of the four who plant the trees in paradise in 3 Baruch 4:7; he helps Eve (together with other angels) to give birth to Cain ... Perhaps the archangel in 1 Thessalonians 4:16 is originally connected with Michael who is portrayed as blowing the trumpet to call to judgment (Apocalypse of Moses 22:1). The 'angel of peace' Compare Testament of Dan 6:1-5; Testament of Asher 6:5; Testament of Benjamin 6:1) identifies the four faces with the four archangels (l Enoch 40:8), i.e., he himself is not to be confused with Michael. The 'interceding angel' (1 Enoch 89:76; 90:14; Testament of Levi 5:6) could well be Michael, but he is not called so, although there are some resemblances: e.g. in Testament of Asher 6:5, entering into, eternal life, or the dualism with 'Belial' in Testament of Benjamin 6:1 ..."
