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 Asher 6:6
Testament of the Twelve PatriarchsFor the latter ends of men do show their righteousness (or unrighteousness), when they meet the angels of the Lord and of Satan. For when the soul departs troubled, it is tormented by the evil spirit which also it served in lusts and evil works. But if he is peaceful with joy he meeteth the angel of peace, and he leadeth him into eternal life.
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 ..."
