The origins of the Zini family are traced back to Rabbi Joseph Yoshto, a student of Isaac Alfasi from Jaén, Spain in northeastern Andalusia.

He has published series of books in Hebrew such as "Olamot BeIhudam" ("Worlds in their Unity"), "Erets Hemdatenu" ("Land of Our Desires").

He also printed new Land of Israel editions of the "Tefilat he-Hadash" siddur and "Mo'adei Hashem" mahzor for the Shalosh Regalim (the Three Pilgrimage Festivals).

At the start of his operations at the Technion, Rabbi Zini acted privately, delivering lectures and organizing events for 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.

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."

[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.

Following the 2006 Lebanon War, Zini wrote: 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."
