I want to add evidence to the Jesus is not Michael thing, for anyone who cares.
I'm shocked that I overlooked some really important detail, which, for me, nails it entirely.
In Daniel 10:13, we know it speaks of Michael as "one of the" foremost or first princes. Which, that in itself would lend credence to this issue. However, more importantly, we should pay attention to who it is that is speaking, the one who had the appearance of a man.
Verses 5 and 6 describe this one who had the appearance of a man. Clothed in linen, hips girded with gold of Uphaz, body like chrysolite, face with the appearance of lightning, eyes like fiery torches, arms and feet like burnished (smooth, glossy, polished) copper, words like the sound of a crowd. Does this sound familiar? Revelation 1:12-15 has a similar description: clothed with a garment that reached to the feet, girded at the breasts with a golden girdle, eyes a fiery flame, feet like fine copper when glowing in a furnace, voice as the sound of many waters. This is none other than the Christ. Thus, in Daniel 10, this one talking to Daniel is the pre-human Jesus, and he is referring to Michael as someone else entirely.
