Daniel 10:19-20

And he said, “O man greatly loved, fear not, peace be with you; be strong and of good courage.” And as he spoke 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? But now I will return to fight against the prince of Persia; and when I go out, behold, the prince of Greece will come.
