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.

I will fill the bow with Ephraim.
And I will stir up your sons, O Zion, against your sons, O Greece;
And I will make you like a warrior’s sword.
