“except Michael, your Prince”
The verse below was spoken by an “angel” of God who was fighting against the “so called gods” (demons, rulers of principalities in the air such as the “Prince of Persia” & the “Prince of Greece”) while Michael is the archangel of God (hence called a “Prince”).
“Then he said, “Do you understand why I came to you? But I shall now return to fight against the prince of Persia; so I am going forth, and behold, the prince of Greece is about to come.
I will tell you what is inscribed in the book of truth: there is none who contends by my side against these except Michael, your prince.” (Daniel 10:20 – 21)
