Daniel 10:19-21

19He said, ‘Do not fear, greatly beloved, you are safe. Be strong and courageous!’ When he spoke to me, I was strengthened and said, ‘Let my lord speak, for you have strengthened me.’ 20Then he said, ‘Do you know why I have come to you? Now I must return to fight against the prince of Persia, and when I am through with him, the prince of Greece will come. 21But I am to tell you what is inscribed in the book of truth. There is no one with me who contends against these princes except Michael, your prince.
