Jude 1:9

“Yet Michael the archangel, etc.] By whom is meant, not a created angel, but an eternal one, the Lord Jesus Christ; as appears from his name Michael, which signifies, “who is as God”: and who is as God, or like unto him, but the Son of God, who is equal with God? and from his character as the archangel, or Prince of angels, for Christ is the head of all principality and power; and from what is elsewhere said of Michael, as that he is the great Prince, and on the side of the people of God, and to have angels under him, and at his command, (<271021>Daniel 10:21 <271201>12:1 <661207>Revelation 12:7). So Philo the Jew f13 calls the most ancient Word, firstborn of God, the archangel; Uriel is…”

“Michael, the archangel--Nowhere in Scripture is the plural used, "archangels"; but only ONE, "archangel." The only other passage in the New Testament where it occurs, is Th1 4:16, where Christ is distinguished from the archangel, with whose voice He shall descend to raise the dead; they therefore err who confound Christ with Michael. The name means, Who is like God? In Dan 10:13 he is called "One ('the first,' Margin) of the chief princes." He is the champion angel of Israel. In Rev 12:7 the conflict between Michael and Satan is again alluded to. about the body of Moses--his literal body. Satan, as having the power of death, opposed the raising of it again, on the ground of Moses' sin at…”

“Yet Michael the archangel ... - This verse has given more perplexity to expositors than any other part of the Epistle; and in fact the difficulties in regard to it have been so great that some have been led to regard the Epistle as spurious. The difficulty has arisen from these two circumstances: Ignorance of the origin of what is said here of Michael the archangel, nothing of this kind being found in the Old Testament; and, (2)The improbability of the story itself, which looks like a mere Jewish fable. Peter 2 Peter 2:2 made a general reference to angels as not bringing railing accusations against others before the Lord; but Jude refers to a particular case - the case of Michael when…”

“Yet Michael - It does not appear whether St. Jude learned this by any revelation or from ancient tradition. It suffices, that these things were not only true, but acknowledged as such by them to whom he wrote. The archangel - This word occurs but once more in the sacred writings, Th1 4:16. So that whether there be one archangel only, or more, it is not possible for us to determine. When he disputed with the devil - At what time we know not. Concerning the body of Moses - Possibly the devil would have discovered the place where it was buried, which God for wise reasons had concealed. Durst not bring even against him a railing accusation - Though so far beneath him in every respect. But simply…”

“1:9 Michael, one of the mightiest of the angels: In Jewish tradition, “archangel” was the highest rank of angel (see also 1 Thes 4:16). Michael is mentioned several other times in Scripture (Dan 10:13, 21; 12:1; Rev 12:7); the story about him fighting with the devil about Moses’ body is not in the Old Testament but is preserved in Jewish tradition (see Assumption of Moses).”

“Michael: It is most probable, that the Apostle took this account concerning Michael, and that of the prophesying of Enoch, from an ancient tradition preserved and well known among the Jews. Dan 10:13, Dan 10:21, Dan 12:1; Rev 12:7 archangel: Th1 4:16 the body: Deu 34:6 durst: Exo 22:28; Isa 36:13-21; Mar 15:29; Luk 23:39, Luk 23:40; Pe1 3:9; Pe2 2:11 The Lord: Ch1 12:17; Isa 37:3, Isa 37:4, Isa 37:10-20; Zac 3:2 Jude 1:10”
