As a rule the only merchandise with which the Ishmaelites loaded their camels was pitch and the skins of beasts. By a providential dispensation they carried bags of perfumery this time, instead of their usual ill-smelling freight, that sweet fragrance might be wafted to Joseph on his journey to Egypt. These aromatic substances were well suited to Joseph, whose body emitted a pleasant smell, so agreeable and pervasive that the road along which he travelled was redolent thereof, and on his arrival in Egypt the perfume from his body spread over the whole land, and the royal princesses, following the sweet scent to trace its source, reached the place in which Joseph was.
Even after his death the same fragrance was spread abroad by his bones, enabling Moses to distinguish Joseph's remains from all others, and keep the oath of the children of Israel, to inter them in the Holy Land.
