John Gill Commentary Genesis 47:30

"but when I sleep with my fathers, thou shalt carry me out of Egypt, and bury me in their burying-place. And he said, I will do as thou hast said." — Genesis 47:30 (ASV)

But I will lie with my fathers
Abraham and Isaac, whose bodies lay in the land of Canaan, where Jacob desired to be buried; partly to express his faith in the promised land, that it should be the inheritance of his posterity; and partly to draw their minds away from continuing in Egypt, and to incline them to think of removing there at a proper time, and to confirm them in the belief of their enjoyment of it; as well as to intimate his desire for, and faith in the heavenly glory he was going to, of which Canaan was a type:

and you shall carry me out of Egypt ;
into the land of Canaan:

and bury me in their burying place ;
in the burying place of his fathers, in the cave of Machpelah, near Hebron; see (Genesis 49:30Genesis 49:31) ;

and he said, I will do as you have said ;
Joseph promised his father to fulfil his request, and do as he had desired of him.
