the word translated as prince also means elder. Michael is a created being, Jesus existed before His birth.
Let us test your conclusion about Michael as a created being.
If Michael is an angel. I can see your point he is a created being, but Michael can never and will never be an angel or a created being. The proof that he’s not is overwhelming. Normally, the word princes and kings are interchangeable.
There are three kings/princes in the Trinity:
1 Father
2 Son
3 Holy Spirit
Daniel 10:13 reads:
“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:...”
In this context, “chief” can be translated: as the “head,” or, the “number one,” or, “one of.” Michael is either the head, the number one, or one of the Trinity.
Still not convince? Did you know names in the Bible have meanings? For instance:
1 Mi-cha-
el means = assuredly is God.
2
Elo-him means = God
3 Im-manu-
el means = God with us
Note the underlined letters “el” denotes God in Hebrew.
There are many more names specially in the Old Testament, like Ezekiel and Joel...etc., but the examples above will suffice.
I pray this helped.
