Sinclair Ferguson: Jesus, The Resurrection, John 11 (32:46)
The sisters and Lazarus seem to be from a family of economic and social significance. That is alluded to when Lazarus dies and a number of Jews from Jerusalem come to be with the family. Further, as mentioned in chapter 11, Mary pours a volume of ointment on the feet of Jesus equivalent to an annual salary. Not likely something a family of lowly means would have laying around the house.
