hmike....The Hebrew word is ml'k "messenger" whereas "Michael" is myk'l....positing a derivation from the former would require assuming metathesis, which is inherently unlikely and is also implausible because -'l is a usual suffix in angelic names.
I was looking at more intertestamental texts today that seem to be quite relevant. Hebrews 2:2 states: "He did not appoint angels to be rulers of the world to come" and this is strikingly close to the following: "And he sanctified them [Israel] and gathered them from all of the sons of man because there are many nations and many peoples, and they all belong to him, but over all of them he caused spirits to rule so that they might lead them astray from following him. But over Israel he did not cause any angel or spirit to rule because he alone is their ruler" (Jubilees 15:31-32). The concept here is clearly related to the notion in Daniel (ultimately rooted in the pre-exilic mythopolitical view in Deuteronomy 32:8-9) that each nation is ruled by angelic "princes", and thus the "angels" here are supernatural "spirits".
I think a middle position between Joseph's interpretation (= hoi aggeloi are not "angels" in ch. 1) and the traditional one (= hoi aggeloi are "angels" in this passage) is actually quite feasible....on the grounds I mentioned several posts ago, that the dead faithful were viewed as existing in heaven in their postmortem state, if not as "angels" at least angel-like. What makes this possibility seem quite feasible are the traditions in the Second Temple period about the levitical priesthood which are precisely along these lines. Consider, again, what Jubilees has to say:
"And he [Jacob] turned to Levi first and he began to bless him first, and he said to him, 'May the God of all, the Lord of ages, bless you and your sons in all ages .... May he draw you and your seed near to him from all flesh to serve in his sanctuary as the angels of the presence and the holy ones. May your sons' seed be like them with respect to honor and greatness and sanctification. And may he make them great in every age' " (Jubilees 31:13-14).
A similar tradition occurs in the Testament of Levi:
"Listen, therefore, concerning the heavens which have been shown to you. The lowest is dark ... In the second are the armies arrayed for the Day of Judgment to work vengeance on the spirits of error and Beliar. Above them are the Holy Ones. In the uppermost heaven of all dwells the Great Glory in the Holy of Holies superior to all holiness. There with him are the archangels who serve and offer propitiatory sacrifices to the Lord in behalf of all the sins of ignorance of the righteous ones. They present to the Lord a pleasing odor, a rational and bloodless oblation. In the heaven below them are the messengers who carry the responses to the angels of the Lord's presence. There with him are Thrones and Authorities; praises to God are offered there eternally....The Most High has given heed to your prayer that you [the sons of Levi] be delivered from wrongdoing, that you should become a son to him, as a minister and priest in his presence" (Testament of Levi 3:2-8, 4:2).
Here the descendents of Levi are pictured as serving as priests in God's presence, just as the "archangels" offer priestly sacrifices in God's presence. They are also referred to as becoming "sons" to God, which echoes the claim in Hebrews 1:5 that God never told any angel that he was his "son", as well as 2:10 and 12:5-8 referring to saved Christians as being "sons" of God. Since Hebrews is steeped in the priestly tradition, it may be addressing or playing with some of these earlier concepts in Jewish literature about the priesthood and the expected priestly Messiah (cf. 11QMelch, which construes the priest Melchizedek as the heavenly "Anointed of the Spirit", to wage the final war against Belial like Michael in 1QM). The idea that Christians would join the angelic assembly in heaven is also expressed in 12:22-23: "You have come to Mount Zion and the city of the living God, the heavenly Jerusalem where the millions of angels have gathered for the festival, with the whole Church in which everyone is a firstborn son and a citizen of heaven". The concept in Revelation, particularly ch. 7, of the "great multitude" of martyrs killed in the Great Tribulation serving as priests in the heavenly sanctuary, also comes readily to mind.
The Testament of Moses also have another fascinating text that might be related to these notions. In describing the imminent end times, ch. 9 introduces the enigmatic figure of Taxo, "a man from the tribe of Levi" who endures the final Great Tribulation and exhorts the faithful to "die rather than transgress the commandments of the Lord of Lords, the God of our fathers. For if we do this, and do die, our blood will be avenged before the Lord" (9:6-7). These words are immediately followed by a description of the eschatological kingdom:
"Then his kingdom will appear throughout all creation. Then the Devil will have an end. Yes, sorrow will be led away with him. Then will be filled the hands of the messenger, who is in the highest place appointed. He will at once avenge them of their enemies....Then you will be happy, O Israel! And you will mount above the necks and the wings of an eagle. All things will be fulfilled. And God will raise you to the heights. He will fix you firmly in the heaven of the stars, in the place of their habitations. And you will behold from on high and you will see your enemies down on the earth. And recognizing them you will rejoice and give thanks, confessing your Creator" (Testament of Moses 10:1-2, 8-10).
This is a most difficult text because it is not clear who Taxo is supposed to be (a Messiah figure? a martyr? symbolic of a group?), who the "his" in "his kingdom" refers to (i.e. to the "Lord" or to Taxo), who the "messenger" is supposed to be, or even whether ch. 10 originally followed ch. 9 or has been dislocated from somewhere else in the text. One helpful fact is that the phrase "filling one's hands" is a technical term referring to the consecration of priests (cf. Exodus 28:41, 29:29, Leviticus 8:33, 21:10; Numbers 3:3, Judges 17:5, 1 Kings 13:33, Testament of Levi 8:10, Joseph and Asenath 27:2, etc.), which makes it all the more plausible that Taxo, the descendent of Levi, is the one who is the "messenger" (nuntius) that is consecrated as a priest and "appointed to the highest place" (in summo constitutus). The Latin nuntius "messenger" may well be a translation of an underlying Greek aggelos, but what is notable is that the "messenger" is appointed to the "highest place" just as Israel itself is raised and established "in the heaven of stars". This may be one reason for considering Taxo as symbolic of Israel, or as its representative. But what is especially striking is the similarity in this scenario and the death-resurrection-exaltation of Jesus Christ in Hebrews 1, Philippians 2, Colossians 1, etc. Taxo urges everyone in faithful Israel to die a martyr's death, and presumably dies himself, and then we have a description of Israel and a priestly (= Levite) messenger being raised to heaven and exalted; the reference to being "appointed to the highest place" recalls Ephesians 1:20-23 which states that God "made him [Jesus] over all things" or Hebrews 1:2-4 which says that the Son took his place "in heaven at the right hand of divine Majesty," making himself "far superior to the angels". So the idea that Jesus, dying a martyr's death, would be exalted to heaven might well have a pre-Christian Jewish basis, as it is also expressed in Revelation.
