ושכבתי עם אבתי BUT I WILL LIE WITH MY FATHERS — This ו of ושכבתי is the connecting link with the beginning of the verse above: Put thy hand beneath my thigh and swear unto me that you will not bury me in Egypt. For I must ultimately lie with my fathers (i.e. die as all my fathers have died) and you shall carry me out of Egypt. One cannot say that “I will lie with my fathers” means “make me lie with my fathers in the cave” (i.e. bury me), for immediately after this it is written “And thou shalt carry me out of Egypt and bury me in their burying place”. Further we find that wherever the term “lying with one’s fathers” is used it denotes dying and not burial. For instance, (1 Kings 2:10) “and David lay with his fathers”, and afterwards it states “and he was buried in the city of David”.

ושכבתי עם אבותי, the matter of “the deceased lying with his fathers,” is the placing the bier with the deceased at the place of the eulogy, surrounded by the mourners and those eulogising him. This is why the same expression is used throughout the Book of Kings, whether describing the burial of kings, the righteous, or the wicked.

ויאמר אנכי אעשה כדבריך. He said: "l will do in accordance with your instructions." Why did Joseph have to announce that he was going to do all this? All he had to do was to place his hand where his father had asked and make the promise and that would be his reply to his father's request. This is what Eliezer did when Abraham made him swear an oath concerning his selecting a wife for Isaac (Genesis 24,9).
