v1: Joseph is overcome with sorrow.
v2-3: Joseph, in the position of authority in Egypt, arranges for Jacob's body to be embalmed. Jacob was esteemed by the Egyptians; they mourned 70 days for him, and also allowed Joseph to return to Canaan to bury him. They also attended his burial (v7), and provided chariots and horsemen to accompany the family (v9).
v7-9: Egyptian practice at the time was to embalm the body and place in a wooden coffin. This was then taken to Canaan for a period of mourning. The fact that Pharoah was represented by dignitaries indicates the respect which Jacob had earned as father to Joseph.
v10-11: The mourning seems particularly intense, as the Canaanites remark on it.
v13: Jacob is buried in the family tomb in the field of Machpelah (23.19; 25.9).
v15-21: Joseph's brothers thought that, with Jacob dead, Joseph would exact revenge upon them for their mistreatment of him. They prepare some "instructions" allegedly left by Jacob (v16), asking Joseph to forgive them (v17). In fulfilment of the prophecy (37.7-8), the brothers bow before Joseph (v18). Joseph assured them of his forgiveness; he harboured no grudge or bitterness; he had seen God's hand upon his life (v19-21).
Man's plans for evil are reversed by God (see Acts 2.23).
v22-26: The writer ends the book with Joseph's death, another 50-60 years later. Joseph made request that he be buried in Canaan; Moses carried his bones out of Egypt (Ex 13.19).
The book ends with some matters 'tied off:' Jacob is dead and buried. Joseph has died; his brothers reconciled and safe.
Yet there are wonderful and far-reaching promises made to Noah, Abraham, Isaac, Jacob, Joseph, which are still to be fulfilled.
The 'ideal' lifespan for an Egyptian was 110 years. This was considered a life truly blessed by God. (A History of Children, Irene Smale.)
