Komentaryo sa Deuteronomio 5:3: Rashi, Ibn Ezra, Sforno & Or HaChaim

לא את אבתינו NOT WITH OUR FATHERS — i.e. not with them alone, כרת ה׳ וגו׳ DID THE LORD MAKE [THIS COVENANT], כי אתנו BUT WITH US etc.

Not with our fathers i.e., not only with our fathers, as in “Your name will no longer be called ‘Yaaqov’” [Genesis 35: 10],

היום כלנו חיים, this is why the covenant has to be made with you who enter the Holy Land, so that you will arrange things in such a manner that future generations who were not present at the time this covenant was made will consider it binding for themselves and conduct themselves accordingly.
