Daniel 10:10-13

And, behold, a hand touched me, which set me upon my knees and upon the palms of my hands. And he said unto me, O Daniel, thou 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 thy heart to understand, and to humble thyself before thy God, thy words were heard: and I am come for thy words’ sake. 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.
