Daniel 10:1, 21

In the third year of Cyrus king of Persia a thing was revealed unto Daniel, whose name was called Belteshazzar; and the thing was true, but the time appointed was long: and he understood the thing, and had understanding of the vision.

But I will shew thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince.
