Daniel 10:13-20

13But the prince of the kingdom of Persia withstood me one and twenty days; and behold, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.

14And I am come to make thee understand what shall befall thy people at the end of the days: for the vision is yet for [many] days.

15And as he was speaking with me according to these words, I set my face toward the ground, and I became dumb.

16And behold, one after the likeness of the sons of men touched my lips; and I opened my mouth and spoke, and said unto him that stood before me, My lord, by reason of the vision my pains are turned upon me, and I retain no strength.

17And how can the servant of this my lord talk with this my lord? for as for me, straightway there remaineth no strength in me, neither is there breath left in me.

18Then there touched me again one like the appearance of a man, and he strengthened me;

19and he said, Fear not, man greatly beloved; peace be unto thee, be strong, yea, be strong. And as he was speaking with me I was strengthened, and I said, Let my lord speak; for thou hast strengthened me.

20And he said, Knowest thou wherefore I am come unto thee? And now I return to fight with the prince of Persia; and when I go forth, behold, the prince of Greece shall come.
