Daniel 10:12 (KJV)

And, behold, an hand touched me, which set me upon my knees and upon the palms of my hands.

And he said unto me, O Daniel, a man greatly beloved, understand the words that I speak unto thee, and stand upright: for unto thee am I now sent. And when he had spoken this word unto me, I stood trembling.

Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words.

But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.

Now I am come to make thee understand what shall befall thy people in the latter days: for yet the vision is for many days.
