Daniel
10:13 (NIV) But the prince of the Persian kingdom resisted me [Gabriel] twenty-one days. Then Michael, one of the chief
princes, came to help me,
because I was detained there with the king of Persia É 20 So he said, "Do you know why I have come to you? Soon I will
return to fight against
the prince of Persia, and when I go, the prince of Greece will come."
