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 ( Genesis 49:29 ) .
When they reached the threshing floor of Atad, near the Jordan, they lamented loudly and bitterly; and there Joseph observed a seven-day period of mourning for his father.
