Daniel 10:13-14
Daniel 10:13-14 NKJV
But the prince of the kingdom of Persia withstood me twenty-one days; and behold, Michael, one of the chief princes, came to help me, for I had been left alone there with the kings of Persia. Now I have come to make you understand what will happen to your people in the latter days, for the vision refers to many days yet to come.”
