By so doing you do something for my sake, in that you grant me the chance of being ransomed; I owe to fortune that my name was drawn, all I owe to you is that my name could be drawn. You have given me the means of obtaining your benefit. For the greater part of that benefit I am indebted to fortune; that I could be so indebted, I owe to you.
