Theory:

     “Forgive me!” said the bearded man in a weak voice, when he saw that the king was awake and was looking at him.
 
     “I do not know you, and have nothing to forgive you for,” said the king.
 
     “You do not know me, but I know you. I am that enemy of yours who swore to revenge himself on you, because you executed his brother and seized his property. I knew you had gone alone to see the hermit, and I resolved to kill you on your way back. But the day passed and you did not return. So I came out from my ambush to find you, and came upon your bodyguard, and they recognized me, and wounded me. I escaped from them, but should have bled to death had you not dressed my wound. I wished to kill you, and you have saved my life. Now, if I live, and if you wish it, I will serve you as your most faithful slave, and will bid my sons do the same. Forgive me!”
