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 those 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 Dan 6:5
Testament of the Twelve PatriarchsTherefore is the enemy eager to destroy all that call upon the Lord. For he knoweth that upon the day on which Israel shall repent, the kingdom of the enemy shall be brought to an end. For the very angel of peace shall strengthen Israel, that it fall not into the extremity of evil. And it shall be in the time of the lawlessness of Israel, that the Lord will not depart from them, but will transform them into a nation that doeth His will, for none of the angels will be equal unto him. And His name shall be in every place in Israel, and among the Gentiles.
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 ..."
