We have here an account of Jacob's funeral. Of the funerals of the kings of Judah, usually, no more is said than this, They were buried with their fathers in the city of David: but the funeral of the patriarch Jacob is more largely and fully described, to show how much better God was to him than he expected (he had spoken more than once of dying for grief, and going to the grave bereaved of his children, but, behold, he dies in honour, and is followed to the grave by all his children), and also because his orders concerning his burial were given and observed in faith, and in expectation both of the earthly and of the heavenly Canaan. Now, 1. It was a stately funeral. He was attended to the grave, not only by his own family, but by the courtiers, and all the great men of the kingdom, who, in token of their gratitude to Joseph, showed this respect to his father for his sake, and did him honour at his death. Though the Egyptians had had an antipathy to the Hebrews, and had looked upon them with disdain (Gen 43:32), yet now, that they were better acquainted with them, they began to have a respect for them. Good old Jacob had conducted himself so well among them as to gain universal esteem. Note, Professors of religion should endeavour, by wisdom and love, to remove the prejudices which many may have conceived against them because they do not know them. There went abundance of chariots and horsemen, not only to attend them a little way, but to go through with them. Note, The decent solemnities of funerals, according to a man's situation, are very commendable; and we must not say of them, To what purpose is this waste? See Act 8:2; Luk 7:12. 2. It was a sorrowful funeral (Gen 50:10, Gen 50:11); standers-by took notice of it as a grievous mourning. Note, The death of good men is a great loss to any place, and ought to be greatly lamented. Stephen dies a martyr, and yet devout men make great lamentations for him. The solemn mourning for Jacob gave a name to the place, Abel-Mizraim, the mourning of the Egyptians, which served for a testimony against the next generation of the Egyptians, who oppressed the posterity of this Jacob to whom their ancestors showed such respect.

And his sons did unto him - This and the thirteenth verse have been supposed by Mr. Locke and others to belong to the conclusion of the preceding chapter, in which connection they certainly read more consistently than they do here.

And his sons did unto him according as he commanded them. Not only Joseph, but all the sons of Jacob were concerned in the burial of him, being all charged by him with it, and who were obedient to his commands as follows; see Gen 49:29.

gen 50:13For his sons carried him into the land of Canaan,.... That is, they took care that he was carried there, as he desired to be; for it cannot be thought that they carried him on their shoulders thither, in like manner as the devout men carried Stephen to his burial, Act 8:2.

and buried him in the cave of the field of Machpelah, &c. the very place where he chose to be buried, Gen 47:29.

they came to the threshing-floor of Atad, &c.--"Atad" may be taken as a common noun, signifying "the plain of the thorn bushes." It was on the border between Egypt and Canaan; and as the last opportunity of indulging grief was always the most violent, the Egyptians made a prolonged halt at this spot, while the family of Jacob probably proceeded by themselves to the place of sepulture.
