Ibn Ezra on Genesis 48:7/אבן עזרא על בראשית מ״ח:ז׳

1[AND AS FOR ME, WHEN I CAME FROM PADDAN.] Rachel died suddenly and I was not able to transport her to the cave of Machpelah and inter her there, as I did with Leah. Jacob told this to Joseph so that he would not be angry with him for requesting that he do for him what he didn’t do for his mother.
