What is a covenant? What is the covenant between God and Israel?
(7) It is not because you are the most numerous of peoples that the LORD set His heart on you and chose you—indeed, you are the smallest of peoples; (8) but it was because the LORD favored you and kept the oath He made to your fathers...
וַיֹּ֨אמֶר יְהוֹשֻׁ֜עַ אֶל־הָעָ֗ם עֵדִ֤ים אַתֶּם֙ בָּכֶ֔ם כִּֽי־אַתֶּ֞ם בְּחַרְתֶּ֥ם לָכֶ֛ם אֶת־יְהוָ֖ה לַעֲבֹ֣ד אוֹת֑וֹ ...
Thereupon Joshua said to the people, “You are witnesses against yourselves that you have by your own act chosen to serve the LORD.”...
Yet, even then...I will not reject them... to destroy them, annulling My covenant with them: for I the LORD am their God.
(ט) אַתֶּ֨ם נִצָּבִ֤ים הַיּוֹם֙ כֻּלְּכֶ֔ם לִפְנֵ֖י יְהוָ֣ה אֱלֹהֵיכֶ֑ם רָאשֵׁיכֶ֣ם שִׁבְטֵיכֶ֗ם זִקְנֵיכֶם֙ וְשֹׁ֣טְרֵיכֶ֔ם כֹּ֖ל אִ֥ישׁ יִשְׂרָאֵֽל׃ (י) טַפְּכֶ֣ם נְשֵׁיכֶ֔ם וְגֵ֣רְךָ֔ אֲשֶׁ֖ר בְּקֶ֣רֶב מַחֲנֶ֑יךָ מֵחֹטֵ֣ב עֵצֶ֔יךָ עַ֖ד שֹׁאֵ֥ב מֵימֶֽיךָ׃ (יא) לְעָבְרְךָ֗ בִּבְרִ֛ית יְהוָ֥ה אֱלֹהֶ֖יךָ וּבְאָלָת֑וֹ אֲשֶׁר֙ יְהוָ֣ה אֱלֹהֶ֔יךָ כֹּרֵ֥ת עִמְּךָ֖ הַיּֽוֹם׃ (יב) לְמַ֣עַן הָקִֽים־אֹתְךָ֩ הַיּ֨וֹם ׀ ל֜וֹ לְעָ֗ם וְה֤וּא יִֽהְיֶה־לְּךָ֙ לֵֽאלֹהִ֔ים כַּאֲשֶׁ֖ר דִּבֶּר־לָ֑ךְ וְכַאֲשֶׁ֤ר נִשְׁבַּע֙ לַאֲבֹתֶ֔יךָ לְאַבְרָהָ֥ם לְיִצְחָ֖ק וּֽלְיַעֲקֹֽב׃ (יג) וְלֹ֥א אִתְּכֶ֖ם לְבַדְּכֶ֑ם אָנֹכִ֗י כֹּרֵת֙ אֶת־הַבְּרִ֣ית הַזֹּ֔את וְאֶת־הָאָלָ֖ה הַזֹּֽאת׃ (יד) כִּי֩ אֶת־אֲשֶׁ֨ר יֶשְׁנ֜וֹ פֹּ֗ה עִמָּ֙נוּ֙ עֹמֵ֣ד הַיּ֔וֹם לִפְנֵ֖י יְהוָ֣ה אֱלֹהֵ֑ינוּ וְאֵ֨ת אֲשֶׁ֥ר אֵינֶ֛נּוּ פֹּ֖ה עִמָּ֥נוּ הַיּֽוֹם׃

Verses 11-12: The purpose of the convocation is to establish the covenant and thereby create a mutual relationship between God and Israel.
Verses 13-14: The covenant binds even future generations; consequently, the punishment for infraction of its terms extends to the third and fourth generation.
those who are not with us here this day. That is, future generations. The reference cannot be to absentees, since verses 9-10 indicate that all are present. According to Midrash Tanchuma, the phrase refers to those who were spiritually present: the souls of all future generations of Jews were present and bound themselves to God by this covenant. In any case, the point of the text is that the mutual commitments made here by God and Israel are binding for all future generations. Ancient Near Eastern treaties likewise stipulate that they are binding on the parties' descendants.
