Daniel 10:18-22

Then this one with human appearance touched me again and strengthened me.

And he said, “You who are treasured, do not be afraid. Peace be to you; take courage and be courageous!” Now as soon as he spoke to me, I felt strengthened and said, “May my lord speak, for you have strengthened me.”

Then he said, “Do you understand why I came to you? But I shall now return to fight against the prince of Persia; so I am leaving, and behold, the prince of Greece is about to come.

However, I will tell you what is recorded in the writing of truth. Yet there is no one who stands firmly with me against these forces except Michael your prince.
