Rabbi Yitzhak Hai Zaga

Rabbi Yitzhak Hai Zaga is a rabbi, attorney, economist and public figure. He is one of the founders and the head of Ruach Yerushalmit, a movement dedicated to disseminating the teachings of Rabbi Abraham Isaac HaCohen Kook. He is married to Tzvia, is the father of ten, and lives in the community of Peduel in Samaria.

Rabbi Zaga studied at the Mercaz HaRav and Shaalvim yeshivot and served as a combat soldier in the Givati Brigade. He holds bachelor's and master's degrees in law and a master's degree in business administration from Bar-Ilan University. For many years he worked as an attorney, strategic adviser and director in leading companies in the Israeli economy.

In his legal work, he promoted the redemption of land in Judea and Samaria and the expansion of settlement. He later founded Lechatchila, a network of monetary law courts intended to resolve civil disputes through arbitration based on Jewish law.

For more than three decades, Rabbi Zaga has taught and disseminated Torah to diverse audiences. Through the Ruach Yerushalmit study hall, his lectures, books and thousands of items published online, he works to make Rabbi Kook's teachings a living Torah that speaks to every sphere of life, from the individual and the family to society, the state, law, the economy and security.

Over the years, he has been active in the public and political arenas. He ran for the leadership of HaBayit HaYehudi and in the Religious Zionism party primaries, and worked to strengthen the state's Jewish identity, settlement, Jewish law and Israeli sovereignty in the Land of Israel.

In 2026, Rabbi Zaga joined the Zehut party led by Moshe Feiglin. Through his work in the party, he seeks to lead a campaign to restore sovereignty and security, confront nationalist crime and internal Arab revolt decisively, reform the judicial system, and establish the Jewish identity of the State of Israel.

Rabbi Zaga brings Zehut a distinctive combination of Torah depth, legal and economic experience, and decades of public service, grounded in the belief that the State of Israel needs not another round of managing its problems, but a complete vision that leads to decision, victory and Jewish renewal.
