Where does the term good Samaritan come from?

The term comes from the Bible and specifically a parable from the gospel of Luke. In that parable, Jesus relates the story of a Samaritan who stopped to assist a Jewish man who was badly beaten and needed food. The parable stands for the basic principles that people should be good neighbors, treat each other civilly and do not refuse to help someone simply because they belong to a different race, religion, or nationality.
