Is character change possible, even in people of a mature age? What sort of man who would sell his own brother into slavery, and then persuade their father that the boy had been eaten by wild animals? Who would sleep with a prostitute but then, finding his widowed daughter-in-law to be pregnant, supposedly as the result of prostitution, condemn her to be burnt to death? That was Judah, who we read about last week. But what happened when Judah found himself face to face with Joseph, his long-lost brother? Is it possible for old dogs to learn new tricks?
