Good catch. I didn't see that.
Interestingly, there's a margin note in the Geneva Bible that agrees with DLH. You probably already know that the Geneva Bible was an entire English translation produced in Switzerland around the time of the Reformation (John Calvin was still alive and in Switzerland) by English refugees running away from the Catholic Mary Tudor (known as "Bloody Mary"). According to this website:
The Geneva Bible was at the foundation of the American Colonies. It was the Bible used in Jamestown and the preferred Bible of the early Pilgrim settlers of New England. The Geneva Bible was the Bible of the leading English writers John Bunyan, William Shakespeare, and John Milton.
The Geneva Bible was a fore-runner to the KJV, and it was probably the reason for King James' authorization of the KJV, because many of the margin notes seemed to deny the king's full authority to do whatever he wanted.
On the possible identification of Michael with Jesus...
These are all the verses that mention Michael by name:
[Dan 10:13, 21 KJV] But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia. ... But I will shew thee that which is noted in the scripture of truth: and [there is] none that holdeth with me in these things, but Michael your prince.
[Dan 12:1 KJV] And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation [even] to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
[Jde 1:9 KJV] Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.
[Rev 12:7 KJV] And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
Jude 1:9 is particularly interesting because it parallels a story in Zechariah, where "the LORD", wanting to rebuke Satan says "the LORD rebuke thee", which is an awkward wording, and is usually counted as support for the Trinity in the Old Testament:
[Zec 3:1-2 KJV] And he shewed me Joshua the high priest standing before the angel of the LORD, and Satan standing at his right hand to resist him. And the LORD said unto Satan, The LORD rebuke thee, O Satan; even the LORD that hath chosen Jerusalem rebuke thee: [is] not this a brand plucked out of the fire?
When compared with Jude 9, and coupled with dispensational thought on the "body of Christ" as opposed to the "body of Moses" (or the Jews under the law), you can see where someone might get the idea that Michael is really Jesus Christ. The only thing that prevents us from going along with it is the title "archangel".
How many archangels are there in the bible? Only Jude 9 identifies one with a name (although the NLT carries that association back into Daniel 12:1 to replace "the great prince"), and it's Michael. Catholics find 7 in their various extra-biblical works, but let's ignore that for now.
I can't really see any problem with identifying Michael with Jesus Christ, but I'm hesitant to do so, for the same reasons as you, probably--it sounds like a degradation of Jesus. But if "archangel" means "head of the angels", and there is only one, then it is an appropriate title for Jesus.
One more thing. Which of the angels ever sit in the presence of God? Gabriel told us he stands in God's presence: Luke 1:19. Dan 12:1 tells us Michael will "stand up" (meaning he will be sitting and change to standing, I suppose) at the time of Jacob's trouble and deliver Daniel's people. Stephen, as he was being stoned, saw Jesus standing up
[Act 7:55 KJV] But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God
yet Jesus said He would be sitting
at the right hand of God:
[Luk 22:69 KJV] Hereafter shall the Son of man sit on the right hand of the power of God.
Why would He stand up? Stephen was in trouble, and it sounds like he was given a vision of Jesus standing up to deliver. Back to Dan 12:1, Michael is described as the one "which standeth for the children of thy people".
I'm not sure...I'd hate to jump right in if it's blasphemous, but the evidence is actually fairly strong. However, if it's Jesus, then it wasn't just some spirit being in heaven that later became Jesus--it was the Son of God, LORD, as shown in Zech 3:1-2.
