I doubt that there is any more well-known parable than the Parable of the Good Samaritan. It has been used, unfortunately, in anti-Jewish polemic over the centuries. But this is a misuse of the parable.
One way of looking at the parable is to see this as Jesus reminding his listeners that focus, while a good thing, can lead us to lose sight of the issues and situations on the periphery of our vision. They are also matters of concern.
