Jamieson, Fausset and Brown on Genesis 46:5

Ge 46:5-27. Immigration to Egypt.

5. And Jacob rose up from Beer-sheba--to cross the border and settle in Egypt. However refreshed and invigorated in spirit by the religious services at Beer-sheba, he was now borne down by the infirmities of advanced age; and, therefore, his sons undertook all the trouble and toil of the arrangements, while the enfeebled old patriarch, with the wives and children, was conveyed by slow and leisurely stages in the Egyptian vehicles sent for their accommodation.
