Daniel 10:18-21 AMPC
Then there touched me again one whose appearance was like that of a man, and he strengthened me.
And he said, O man greatly beloved, fear not! Peace be to you! Be strong, yes, be strong. And when he had spoken to me, I was strengthened and said, Let my lord speak, for you have strengthened me.
Then he said, Do you know why I have come to you? And now I will return to fight with the [hostile] prince of Persia; and when I have gone, behold, the [hostile] prince of Greece will come.
But I will tell you what is inscribed in the writing of truth or the Book of Truth. There is no one who holds with me and strengthens himself against these [hostile spirit forces] except Michael, your prince [national guardian angel].
