Education and research in Jewish disciplines

Rabbi Zini dedicates his time to disseminating Torah to the public. He began a program at the Technion which enabled students to add Torah study to their science and engineering studies.

Zini's research in Torah-related fields focuses on books of the Geonim. Some of his research has been published in books, pamphlets, and articles. He has published series of books in Hebrew such as "Olamot BeIhudam" ("Worlds in their Unity"), "Erets Hemdatenu" ("Land of Our Desires"). He has published chidushim (original Torah thoughts) of Rashbatz on tractates Rosh Hashanah and Kinnim of the Babylonian Talmud, as well as "Magen Avot," Rashbatz' commentary on Pirkei Avot. Similarly, he has published research on the history of halakha and the editing of the Talmud, such as "Rabanan Savora'ei ve-Klalei ha-Halakha" ("The Savoraim and the Rules of Halakha"). He has also published letters of Elijah Benamozegh, Hebrew translations of Professor Emmanuel Levinas, Hebrew translations of Rabbi Léon Ashkenazi (with whom he was particularly close), and others. He also print*Olamot be-Ihudam – ed new land of Israel editions of the "Tefilat he-Hadash" siddur and "Mo'adei Hashem" mahzor for the Shalosh Regalim (the Three Pilgrimage Festivals).

Zini advocates for the joining of Torah study and science, claiming that it is fundamentally impossible for them to be contradictory. He opposes the methodology employed by Professor Nathan Aviezer in Aviezer's book "Bereishit Bara." The book uses scientific fact to prove the accuracy of the Torah, while Zini does not believe that such explanations are necessary.

Zini's method of Torah study is based on a broad knowledge of the literature of the Tanaim and Amoraim, a deeper study of the earlier sources in Midrash halakha, and only then a discussion of the words of the Talmud and Rishonim. In Talmud study, Zini uses the writings of the Geonim.

Zini is also involved in philosophy. He met Professor Emmanuel Levinas in France and translated some of his essays. He published four of Levinas' articles in a pamphlet entitled "Divrei Emmanuel" ("The Words of Emmanuel") and cites him in his lectures.

Encouragement of Aliyah and absorption into Israel

Rabbi Zini immigrated to Israel in 1970. He moved to Bnei Brak and began finishing his doctoral studies at the Technion. On his return to the Technion as an associate senior lecturer, Zini began activities to draw in the new immigrants from amongst the student body. A group of French immigrants formed the original basis of the minyan at the Technion synagogue.

Rabbi of the Technion

At the start of his operations at the Technion, Rabbi Zini acted privately, delivering lectures and organizing events for students. In 1980, the previous rabbi of the Technion, Rabbi Aharon She'ar-Yashuv, left the institution, recommending that Zini take his place.

As rabbi of the Technion, Zini headed the organization of religious students there, called Ahvat Aharon. He opposed the plan to grant homosexual couples dorms reserved for married students. Once this plan was put into action, Zini ruled that the mezuzot must be removed from any of those dorms that were given to homosexual couples, though the institution did not comply.^[1]

In 2013, on reaching retirement age, he left his position.

Political stance

Rabbi Zini is well known within the world view that sees the land of Israel as one of the foundations of Judaism, and it is within this world view that his political stance manifests itself. In November 1994, during the harsh debates within Israeli society over the Oslo Accords, he said in his weekly broadcast on Israeli news station Arutz Sheva: "Apparently God knows why the ways of the evildoers who currently run our country have succeeded, for apparently we and you did not do what He expected of us...Meanwhile, of the one primarily responsible for the deterioration of the situation, Mr. Rabin, it is said disgrace on your holiday tomorrow and those who celebrate with you, and may it be God's will to save us quickly from you and then there will be much peace for those who love His name and Torah."^[2]

In the libel suit which Zini brought against the local newspaper "Kolbo," the judge ruled that the paper was guilty of libel against Zini, but only awarded him 1,000 NIS compensation, explaining: "From the material that is presented, the image arises of a man with extreme opinions, who is not averse to [making] statements bordering on incitement, using language that approaches—if not reaches—verbal abuse," and adding: "And this is not a case of an innocent man upon whom guilt of incitement was cast. His opinions and style arouse hatred and separatism while causing difficult injuries to large parts of the population that do not share his world view, and the creation of polarization within society as directly connected to the advertisement under discussion should be taken into account when awarding the compensation." Zini's appeal on the amount of compensation was rejected by the district court.^[2]

One of Zini's essays appears in "Baruch ha-Gever" (a book written in memory of Baruch Goldstein) granting legitimacy to Rabbi Ido Elba's article "Beirur Halakhot Harigat Goy" ("An Inquiry into the Halakhot of Killing Gentiles"), an article which the Supreme Court of Israel deemed an inciter of racism.

In an article published on 12 August 1995 in the newspaper "Aleh," Zini wrote: "An ordinance of evacuation of civilian settlements is not only an illegal ordinance, but also an ordinance that assists the enemy... Any ordinance that assists the enemy... Any order of evacuation will be considered as carrying out the job of the enemy who desires the execution of this ordinance."

Zini opposed the statements of Rabbi Elazar Shach and the halakhic rulings of Rabbi Ovadia Yosef regarding the giving up of settlements in the West Bank and Gaza. He published a pamphlet entitled "Erets Hemdatenu" in which he argued that the sources cited by Rabbi Yosef to prove the permissibility of returning settlements in fact prove the opposite.

Following the 2006 Lebanon War, Zini wrote:

One conclusion presents itself immediately, and that is the obligation that falls upon this wonderful generation, which managed with a high hand this battle with supreme dedication the likes of which we have not seen in 2000 years, to throw in history's trash bin this government, which is entirely a collection of scraps collected by a collector of weak politicians ready to [do] anything, a tyrannical collector who crushed in his path all ethical values and all national values, all to save his skin in the justice system which—as in the statement of former commander-in-chief Bugi Yaalon—apparently does not know mercy other than with its friends and friends of friends.

Prior to the 2009 Israeli election, Zini wrote: "At least two goals must stand before our eyes in these elections: The first, support for those who defend the Torah and the Jewish identity, and the second, support for all those who defend the land of Israel and oppose with all their might a chain of terrible concessions that have already brought about enough bloodshed and enough disasters for the entire Israeli reality." He recommended voting for The Jewish Home party or the National Union and was careful to note that "these matters are not the opinion of the other institution at which I work."
