Origin of Ethics

(22) Ben Bag Bag said: Turn it over, and [again] turn it over, for all is therein.

1) Rabbi Yishmael says: The Torah is expounded through thirteen methods:

1. Kal va-ḥomer: a minore ad maius - an argument that denotes an inference from smaller to bigger and vice versa
2. Gezerah shavah: an anology or inference from one verse to another
3. Binyan av: Rules deduced from a single passage of Scripture and rules deduced from two passages.
4. Kelal u-Peraṭ: The general and the particular.
5. u-Peraṭ u-kelal: The particular and the general.
6. Kelal u-Peraṭ u-kelal: The general, the particular, and the general.
7. The general which requires elucidation by the particular, and the particular which requires elucidation by the general.
8. The particular implied in the general and excepted from it for pedagogic purposes elucidates the general as well as the particular.
9. The particular implied in the general and excepted from it on account of the special regulation which corresponds in concept to the general, is thus isolated to decrease rather than to increase the rigidity of its application.
10. The particular implied in the general and excepted from it on account of some other special regulation which does not correspond in concept to the general, is thus isolated either to decrease or to increase the rigidity of its application.
11. The particular implied in the general and excepted from it on account of a new and reversed decision can be referred to the general only in case the passage under consideration makes an explicit reference to it.
12. Deduction from the context.
13. When two Biblical passages contradict each other the contradiction in question must be solved by reference to a third passage.

(1) The LORD spoke to Moses: (2) See, I have singled out by name Bezalel son of Uri son of Hur, of the tribe of Judah. (3) I have endowed him with a divine spirit of skill, ability, and knowledge in every kind of craft; (4) to make designs for work in gold, silver, and copper, (5) to cut stones for setting and to carve wood—to work in every kind of craft. (6) Moreover, I have assigned to him Oholiab son of Ahisamach, of the tribe of Dan; and I have also granted skill to all who are skillful, that they may make everything that I have commanded you: ...(12) And the LORD said to Moses: (13) Speak to the Israelite people and say: Nevertheless, you must keep My sabbaths, for this is a sign between Me and you throughout the ages, that you may know that I the LORD have consecrated you. (14) You shall keep the sabbath, for it is holy for you. He who profanes it shall be put to death: whoever does work on it, that person shall be cut off from among his kin. (15) Six days may work be done, but on the seventh day there shall be a sabbath of complete rest, holy to the LORD; whoever does work on the sabbath day shall be put to death.

(19)You shall not boil a kid in its mother’s milk.

The school of Rabbi Yishmael taught: The Torah states three times: “You shall not cook a kid in its mother’s milk” (Exodus 23:19, 34:26; Deuteronomy 14:21). One verse serves to teach the prohibition against eating meat cooked in milk, and one serves to teach the prohibition against deriving benefit from it, and one serves to teach the prohibition against cooking meat in milk.

And this is known as the oven of akhnai... The Sages taught: On that day, when they discussed this matter, Rabbi Eliezer answered all possible answers in the world to support his opinion, but the Rabbis did not accept his explanations from him. After failing to convince the Rabbis logically, Rabbi Eliezer said to them: If the halakha is in accordance with my opinion, this carob tree will prove it. The carob tree was uprooted from its place one hundred cubits, and some say four hundred cubits. The Rabbis said to him: One does not cite halakhic proof from the carob tree. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the stream will prove it. The water in the stream turned backward and began flowing in the opposite direction. They said to him: One does not cite halakhic proof from a stream. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, the walls of the study hall will prove it. The walls of the study hall leaned inward and began to fall. Rabbi Yehoshua scolded the walls and said to them: If Torah scholars are contending with each other in matters of halakha, what is the nature of your involvement in this dispute? The Gemara relates: The walls did not fall because of the deference due Rabbi Yehoshua, but they did not straighten because of the deference due Rabbi Eliezer, and they still remain leaning. Rabbi Eliezer then said to them: If the halakha is in accordance with my opinion, Heaven will prove it. A Divine Voice emerged from Heaven and said: Why are you differing with Rabbi Eliezer, as the halakha is in accordance with his opinion in every place that he expresses an opinion? Rabbi Yehoshua stood on his feet and said: It is written: “It is not in heaven” (Deuteronomy 30:12). The Gemara asks: What is the relevance of the phrase “It is not in heaven” in this context? Rabbi Yirmeya says: Since the Torah was already given at Mount Sinai, we do not regard a Divine Voice, as You already wrote at Mount Sinai, in the Torah: “After a majority to incline” (Exodus 23:2). Since the majority of Rabbis disagreed with Rabbi Eliezer’s opinion, the halakha is not ruled in accordance with his opinion. The Gemara relates: Years after, Rabbi Natan encountered Elijah the prophet and said to him: What did the Holy One, Blessed be He, do at that time, when Rabbi Yehoshua issued his declaration? Elijah said to him: The Holy One, Blessed be He, smiled and said: My children have triumphed over Me; My children have triumphed over Me.
