Daniel 10:19-20

He said, “O man of high esteem, do not be afraid. Peace be with you; take courage and be courageous!” Now as soon as he spoke to me, I received strength 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 going forth, and behold, the prince of Greece is about to come.
