This is the familiar story of the Good Samaritan.  This was acrtually extremely scandalous for Jesus to use this imagery.  Amy Jill Levine, Jewish New Testament Scholar at Vanderbilt, suggests that the image is someone coming to your rescue, that was so detested, that you would just as soon die rather than be helped by him.  Wow.  

This is an excellent text for us to examine in this most hostile of times.  How do we learn to listen to each other in a way to understand rather than to hate and reject?
