In chapter 14 what does the judge do before the duel in regards to Tom? How does he justify this action? How does Tom find out about it and what is his respond?

Before leaving for the duel the Judge has a change of heart about Tom. The judge feels partly responsible for Tom's cowardice. He feels that he "indulged him to his hurt, instead of training him up severely, and making a man of him." The judge redraws his will in case he gets murdered in the duel. Tom sees the Judge writing something and examines it after the Judge leaves. Tom discovers that he has, "got the fortune again."
