What did Rivkah mean when she said "Alai Kilelascha Beni"?
Targum Yonasan and Seforno: She meant that, if Yitzchak would bless him and his children, they will be blessed, but if he curses him, then the curses will rebound on to her. 1
Rashbam, Moshav Zekenim and Targum Onkelos: She meant that she had been told prophetically 2 that he would not be cursed!" 3
Divrei Eliyahu and Kol Eliyahu (in 42:36): She meant that she knew prophetically that Ya?akov?s curses (great afflictions) will be "Alai' (an acronym for Eisav, Lavan, Yosef) exclusively. 4
Ohr ha'Chayim: Just now, you mentioned a curse on yourself. A Chacham's curse is fulfilled, even if it was conditional and the condition was not fulfilled! I caused this; I accept the result on myself. "B?ni" clarifies that she does not discuss a curse that Yitzchak might give.
Malbim: If he will want to curse you, tell him that I commanded you to do so, and his anger will be directede at me. He will know that you did not do so amidst desire for this world, only because I commanded you. He will not curse you, especially since there was the prophecy "v'Rav Ya'avod Tza'ir" (25:23). You bought the Bechorah, but this does not make you the 'Rav' that must serve the younger. For this, Eisav is still the older.
Like we find with Shlomoh ha'Melech, who took upon himself the curses of Yo'av, which later materialized, as recorded in Sanhedrin 48b; or, because Ya?akov did what he did at her behest. (EC).
Ha'KEisav veha'Kabalah: Mechilta of R. Shimon says that the Shechinah told her that Yitzchak commanded Eisav - 'Ani Metzavah Osach' (27:8) refers to the Shechinah. This combined with the prophecy of Shem, "v'Rav Ya'avod Tza'ir" (25:23).
Ha'KEisav veha'Kabalah: ?Alai? refers to removal. I have no concern lest he curse you.
Divrei Eliyahu and Kol Eliyahu, ibid.: That no additional curse will come from this - Refer to 42:36:151:2) - which explains why she did not say that Yitzchak would nooit curse him. The question remains however, that the curse of Dinah is omitted?
