Devarim 29: Covenants of Future Past

Moshe’s final farewell address commences in chapter 29. He begins by reaffirming the covenant of the Torah itself:“I make this covenant, with its sanctions—not with you alone, but both with those who are standing here with us this day before our God and with those who are not with us here this day” (verse 13).לֹא אִתְּכֶם לְבַדְּכֶם אָנֹכִי כֹּרֵת אֶת־הַבְּרִית הַזֹּאת וְאֶת־הָאָלָה הַזֹּאת׃כִּי אֶת־אֲשֶׁר יֶשְׁנוֹ פֹה עִמָּנוּ עֹמֵד הַיּוֹם לִפְנֵי ה׳ אֱלֹהֵינוּ וְאֵת אֲשֶׁר אֵינֶנּוּ פֹה עִמָּנוּ הַיּוֹם(Deuteronomy 29:13–14)The Talmud explains that “those not present” refers to converts who are not currently part of the Israelite nation (Shabbat 146a). The Midrash says that this verse alludes to the fact that the souls of all future generations of Israelites/Jews were present that day. “Those who are not standing with us” were actually present at this moment so that they too would be bound by the covenant. They may not have been physically there, but they were spiritually there.The idea of a future covenant for those not physically present was not new. The Rav points out that Avimelech had Avraham swear on behalf of his children and grandchildren in Genesis 21:23. People of the ancient world understood the importance of binding future generations.This chain of passing the covenant forward is immortalized in the opening Mishnah of Avot: “Moses received the Torah at Sinai and transmitted it to Joshua…” and continues through rabbinic authority to this day. This creates an incentive for past generations to preserve the mesorah, knowing that their descendants remain bound by God’s covenant. At the same time, the covenant anchors future generations to the mesorah of the past. For example, communities outside Israel still observe two days of Yom Tov despite a fixed calendar, based on the Talmudic principle “minhag avoteinu b’yadeinu.” This reaching backward and forward creates a stable foundation that keeps the Torah and God’s covenant alive.
