Hassidout sur Le Deutéronome 5:25

וַיִּשְׁמַ֤ע יְהוָה֙ אֶת־ק֣וֹל דִּבְרֵיכֶ֔ם בְּדַבֶּרְכֶ֖ם אֵלָ֑י וַיֹּ֨אמֶר יְהוָ֜ה אֵלַ֗י שָׁ֠מַעְתִּי אֶת־ק֨וֹל דִּבְרֵ֜י הָעָ֤ם הַזֶּה֙ אֲשֶׁ֣ר דִּבְּר֣וּ אֵלֶ֔יךָ הֵיטִ֖יבוּ כָּל־אֲשֶׁ֥ר דִּבֵּֽרוּ׃

L’Éternel entendit les paroles que vous m’adressiez, et il me dit: "J’ai ouï la voix de ce peuple, les paroles qu’il t’adresse: tout ce qu’ils ont dit est bien dit.

Sefat Emet

It is written “And Elohim said...saying”, meaning: the children of Israel said words like these to themselves. It’s also written “who gave us a Torah of truth, and within us, planted eternal life”--this refers to Oral Torah, the unique quality of Torah which is Israel’s. They have a unique intellectual approach to understand secrets within the Torah which are hidden and not explicit within the Torah itself.
