Daniel 10:19-20

“Don’t be afraid,” he said, “for you are very precious to God. Peace! Be encouraged! Be strong!” As he spoke these words to me, I suddenly felt stronger and said to him, “Please speak to me, my lord, for you have strengthened me.” He replied, “Do you know why I have come? Soon I must return to fight against the spirit prince of the kingdom of Persia, and after that the spirit prince of the kingdom of Greece will come.
