There were two kings in the parts of Greece, and one of them was more
powerful than the other. They went into battle together: the more
powerful one lost.
He went home and shut himself into a room, wondering if he had not
dreamed, and soon began to believe he had not fought at all.
Meanwhile the angel of God came to him, and said: how are you? Of what
are you thinking? You have not dreamed, but have fought indeed and were
beaten.
And the king looked upon the angel and said: how can that be? I had
thrice as many troops as he; and the angel replied: and yet it has come
to pass, since you are an enemy of God.
Then the king replied: oh, is my enemy then such a friend of God that
he has beaten me for that reason?
No, said the angel, for God revenges Himself upon His enemies by means
of His enemies. Go you once more with your army, and you shall defeat
him even as he defeated you.
Then he went and fought anew with his foe, and defeated him and
captured him as the angel had foretold.
