Daniel 10:13,20 Prince of Persia
Deut: 32:9 “When the Most High divided the nations, when he separated the sons of Adam, he set the bounds of the nations according to the number of the angels of God. And his people Jacob became the portion of the Lord, Israel was the line of his inheritance.” (Deuteronomy 32:7-9 Jerome’s version of the Septuagint)
The administration of the various nations has been parcelled out among a corresponding number of angelic powers
I only came across 2 mentioned in the Hebrew Bible
Prince (sar) of Persia- It took an extra powerful Archangel (Michael) to kick some ass.
Prince (sar) of Greece
Prince of Israel-Michael the Archangel
Perhaps some books of the Apocrapha may have more info on these princes???
