פירוש על בראשית 49:30

לאחוזת קבר, they will not be able to challenge my right to be buried there.

אשר קנה אברהם, seeing that they had already spent many years in a foreign land, he felt it necessary to remind them that that burial plot was legally theirs. Seeing that already two generations of the patriarchs had been buried there, there was no legal way anyone could now challenge the ownership of this cave.

במערה, we have explained on Genesis 25,10 why this mention of the cave of Machpelah as the patriarchs’ burial site is mentioned so many times in the Torah as if we did not know already.
