Now there remains to complete what we explained (in section 16) about the reason the Torah was not given to the forefathers: The commandment “and love your fellow as yourself” is the pivot of the whole Torah and around which all the mitzvot revolve as they clarify and interpret this commandment. Since this commandment cannot be observed by individuals alone, but only through prior consent of an entire nation; therefore the matter [of the nation accepting it] extended until their exodus from Egypt when they were suited to fulfill the commandment. And then they were first asked if each and every one of the nation agreed to take this commandment upon himself or herself. And once they agreed to it, they were given the Torah. (Examine section 16 carefully.)

However, it still must be clarified: Where do we find in the Torah that the children of Israel were asked this question and that they agreed to it prior to receiving the Torah?
