חלק שישי: חנוכה-מצוות דרבנן

If a case is too baffling for you to decide, be it a controversy over homicide, civil law, or assault—matters of dispute in your courts—you shall promptly repair to the place that your God ה' will have chosen, and appear before the levitical priests, or the magistrate in charge at the time, and present your problem. When they have announced to you the verdict in the case, you shall carry out the verdict that is announced to you from that place that ה' chose, observing scrupulously all their instructions to you. You shall act in accordance with the instructions given you and the ruling handed down to you; you must not deviate from the verdict that they announce to you either to the right or to the left. Should either party [to the dispute] act presumptuously and disregard the priest charged with serving there your God ה', or the magistrate, that party shall die. Thus you will sweep out evil from Israel: all the people will hear and be afraid and will not act presumptuously again.

Most coffins have a handbreadth of space. Consequently, their impurity does not spread above the coffin. However, the Sages issued a decree regarding coffins in which there is a handbreadth of space because of those coffins in which there is not. Nevertheless, due to respect for kings, the Sages did not issue a decree in a case involving them and the priests were permitted to jump over the coffins, as it is permitted by Torah law. Therefore, there is no proof from here regarding the question of whether or not human dignity overrides Torah law.

The Supreme Sanhedrin in Jerusalem are the essence of the Oral Law. They are the pillars of instruction from whom statutes and judgments issue forth for the entire Jewish people. Concerning them, the Torah promises Deuteronomy 17:11: "You shall do according to the laws which they shall instruct you...." This is a positive commandment.
Whoever believes in Moses and in his Torah is obligated to make all of his religious acts dependent on this court and to rely on them. Any person who does not carry out their directives transgresses a negative commandment, as Ibid. continues: "Do not deviate from any of the statements they relate to you, neither right nor left."
Lashes are not given for the violation of this prohibition, because it also serves as a warning for a transgression punishable by execution by the court. For when a sage rebels against the words of the court, he should be executed by strangulation, as the following verse states: "A person who will act deliberately...."
We are obligated to heed their words whether they:
a) learned them from the Oral Tradition, i.e., the Oral Law,
b) derived them on the basis of their own knowledge through one of the attributes of Biblical exegesis and it appeared to them that this is the correct interpretation of the matter,
c) instituted the matter as a safeguard for the Torah, as was necessary at a specific time. These are the decrees, edicts, and customs instituted by the Sages.
It is a positive commandment to heed the court with regard to each of these three matters. A person who transgresses any of these types of directives transgresses a negative commandment. This is derived from the continuation of the above verse in the following manner: "According to the laws which they shall instruct you" - this refers to the edicts, decrees, and customs which they instruct people at large to observe to strengthen the faith and perfect the world. "According to the judgment which they relate" - this refers to the matters which they derive through logical analysis employing one of the methods of Biblical exegesis. "From all things that they will tell you" - This refers to the tradition which they received one person from another. There can never be any difference of opinion with regard to matters received through the Oral Tradition. Whenever there arises a difference of opinion with regard to a matter that shows that it was not received in the tradition from Moses our teacher.
The following principles apply with regard to matters derived through logical analysis. If the entire body of the Supreme Sanhedrin agrees with regard to them, their consent is binding. If there is a difference of opinion, we follow the majority and decide the matter according to the majority. Similarly, with regard to the decrees, edicts, and customs, if a portion of the judges perceived that it was necessary to issue a decree, institute an edict, or establish a custom for the people, and a portion perceived that it is not appropriate to issue this decree, institute this edict, or establish this custom, the judges should debate the matter back and forth. Afterwards, a vote is called, and we follow the majority and execute the matter according to the decision of the majority.

And what blessing does one recite? He recites: Who has made us holy through His commandments and has commanded us to light the Hanukkah light. The Gemara asks: And where did He command us? The mitzva of Hanukkah is not mentioned in the Torah, so how is it possible to say that it was commanded to us by God? The Gemara answers that Rav Avya said: The obligation to recite this blessing is derived from the verse: “You shall not turn aside from the sentence which they shall declare unto you, to the right, nor to the left” (Deuteronomy 17:11). From this verse, the mitzva incumbent upon all of Israel to heed the statements and decrees of the Sages is derived. Therefore, one who fulfills their directives fulfills a divine commandment. Rav Neḥemya said that the mitzva to heed the voice of the Elders of Israel is derived from the verse: “Ask your father, and he will declare unto you, your Elders, and they will tell you” (Deuteronomy 32:7).

Similarly, with regard to all the Rabbinic mitzvot - both the mitzvot that the Rabbis established as obligations - e.g., regarding the megillah, lighting Shabbat candles, and lighting Chanukah candles - and the mitzvot that are not obligations - e.g., an eruv or washing hands - one should recite a blessing before performing them, [praising God] "who has sanctified us with Your commandments and commanded us….”
Where has He commanded us [to fulfill these commandments]? In the Torah, which states [Deuteronomy 17:11]: "Act [according to the judgment] they relate to you." [Based on this Biblical verse, the blessing recited before fulfilling a Rabbinical commandment] can be interpreted as follows: Who has sanctified us with Your commandments and commanded us to listen to these [sages] who have commanded us to light Chanukah candles or read the megillah. The same applies regarding all Rabbinic commandments.
