Daniel 10:12–13

Then he continued, “Do not be afraid, Daniel. Since the first day that you set your mind to gain understanding and to humble yourself before your God, your words were heard, and I have come in response to them. But the prince of the Persian kingdom resisted me twenty-one days. Then Michael, one of the chief princes, came to help me, because I was detained there with the king of Persia.

“Don’t be afraid, Daniel,” he said to me, “for from the first day that you purposed to understand and to humble yourself before your God, your prayers were heard. I have come because of your prayers. But the prince of the kingdom of Persia opposed me for twenty-one days. Then Michael, one of the chief princes, came to help me after I had been left there with the kings of Persia.

Then he said, “Don’t be afraid, Daniel. Since the first day you began to pray for understanding and to humble yourself before your God, your request has been heard in heaven. I have come in answer to your prayer. But for twenty-one days the spirit prince of the kingdom of Persia blocked my way. Then Michael, one of the archangels, came to help me, and I left him there with the spirit prince of the kingdom of Persia.

And he said to me, “You must not fear, Daniel, for from the first day that you set your heart to understand and to humble yourself before your God, your words were heard, and I myself have come because of your words. But the prince of the kingdom of Persia stood before me for twenty-one days. And look, Michael, one of the chief princes, came to assist me, and I left him there beside the king of the Persians.

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.
