But the prince of the kingdom of Persia opposed me for 21 days. Then Michael, one of the chief princes, came to help me after I had been left there with the kings of Persia.

At that time
Michael the great prince
who stands watch over your people will rise up.
There will be a time of distress
such as never has occurred
