“Daniel” x, 13: “But the prince of the kingdom of the
Persians resisted me for one-and-twenty days: And behold Michael, one of
the chief princes, came to help me, and I remained there by the King of the
Persians.” The Prince of the Persians is the angel guardian of Persia:
who, according to his office, seeking the spiritual good of the Persians,
was desirous that many of the Jews should remain among them.
