Create an image by interpreting a scene from Luke 15:2 in the Bible. The image should illustrate the traditional garb of Pharisees and scribes showing expressions of disapproval, while a man calmly accepts and dines with individuals who are visibly marked as outcasts or 'sinners'. Reflect the subtleties and tension of the scene in a style that uses the digital art medium. Keep the palette muted and somber as was often the characteristics of narrative paintings during the Renaissance era.
