Ramban on Genesis 35:12/רמב"ן על בראשית ל״ה:י״ב

אוְאֶת הָאָרֶץ אֲשֶׁר נָתַתִּי לְאַבְרָהָם וּלְיִצְחָק לְךָ אֶתְּנֶנָּה כַּאֲשֶׁר נְתַתִּיהָ לָהֶם כֵּן אֶתְּנֶנָּה לְךָ, יִרְמֹז זֶה לַשְּׁבוּעָה, כִּי לָהֶם נִתְּנָה בִּשְׁבוּעָה שֶׁלֹּא יִגְרֹם הַחֵטְא אֲבָל לוֹ נִתְּנָה מִתְּחִלָּה בְּלֹא שְׁבוּעָה, וְזֶהוּ שֶׁאוֹמֵר בְּכָל מָקוֹם (שמות לג א ועוד) "אֲשֶׁר נִשְׁבַּעְתִּי לְאַבְרָהָם לְיִצְחָק וּלְיַעֲקֹב". אוֹ שֶׁיִּהְיֶה הִכָּפֵל הַנְּבוּאָה לוֹ לִשְׁבוּעָה, כַּאֲשֶׁר פֵּרַשְׁתִּי כְּבָר:
1AND THE LAND WHICH I GAVE UNTO ABRAHAM AND ISAAC, TO THEE I WILL GIVE IT. “As I have given it to them so will I give it to you.” This alludes to an oath, for the land was given to them with an oath so that sin should not cause annulment of the gift, but to Jacob it was originally given without an oath. It is this which Scripture refers to when it says in all places, the land of which I swore unto Abraham, to Isaac, and to Jacob.198 It may that the repetition of the prophecy, [mentioned above, 28:13, and repeated here], constitutes an oath, as I have already explained.199
