Then said he, Know you why I come unto you? and now will I return to fight with the prince of Persia: and when I have gone forth, lo, the prince of Greece shall come.
All Commentaries on Daniel 10:20 Go To Daniel 10
Jerome
AD 420
He means, "I myself was departing (p. 557) from God's presence in order to announce to thee [reading tibi for the inappropriate ubi] the events which are to befall thy people in the last days; and yet I am still not secure, since the prince of the Persians stands to plead against the granting of thy petitions and the acceptance of my advocacy on thy behalf. And behold, the prince of the Greeks, or Macedonians, had just come, and he entered in before God's presence to lodge accusation against the prince of the Medes and Persians, in order that the kingdom of the Macedonians might succeed in their place." Truly marvelous are the secret counsels of God, for it indeed came to pass that after the Jewish people had been freed from captivity, Alexander, king of the Macedonians, slew Darius and overthrew the kingdom of the Persians and Medes, so that the prince of the Greeks did overcome the prince of the Persians.
