Sir, thanks to you my friend and I have been freed from paying some awful penalties today. Instead of giving the Jew the three thousand ducats he's owed, we give it to you in gratitude for your kind efforts.
And even then we're still indebted to you. We owe you love and service forever.
Being satisfied with a job well done is payment enough. In saving you I consider myself well paid. My thoughts were never on money.
I hope you'll recognize me when we meet again. I wish you well. Now, I've got to go.
