The household of Martha, Mary and Lazarus is well known to us from the Gospels, where they are described as "sisters" and their brother Lazarus. They are also known to us as Jesus' friends, and their home as a place he visited for some rest and hospitality. The problem is, that the story is perhaps too familiar: we are so used to hearing of them and their home since childhood, that we automatically accept the words and visualize the family in modern terms, just as we did as children. To really understand the significance of this family, we need to consider the social context.
