Charles Ellicott Commentary Genesis 50:26

"So Joseph died, being a hundred and ten years old: and they embalmed him, and he was put in a coffin in Egypt." — Genesis 50:26 (ASV)

A coffin. —The word means a case or chest of wood. The mummy-cases were generally of sycamore-wood. As it would not be possible for the Israelites, now that their great protector was no more, to go with a military escort to Hebron to bury him, Joseph orders that his embalmed body should be placed in some part of Goshen, from where it would be easy to remove it when the time of deliverance had arrived. And his wish was fulfilled, for Moses took the bones of Joseph with him (Exodus 13:19), and Joshua buried them in Shechem, in the piece of ground which Jacob had given to him (Joshua 24:32).

With the death of Joseph ends the preparation for the formation of a chosen race. Summoned from a remote city upon the Persian Gulf to Palestine, Abraham had wandered there as a stranger, and Isaac and Jacob had followed in his steps. But in Palestine the race could never have multiplied largely, for there were races already there too powerful to permit their rapid increase.

Abraham and Lot, Esau and Jacob had been compelled to separate; but now, under Joseph, they had been placed in a large, fertile, and nearly uninhabited region. The few who lived there were, as far as we can judge, of the Semitic stock, and whatever immigrants came from time to time were also of the same race, and were soon enrolled in the “taf” of some noble or chief. And thus all was ready for their growth into a nation; and when we next read of them they had multiplied into a people so vast that Egypt was afraid of them.
