Hayim was born in Tel Aviv on 22.12.1930. He studied in cheder in the Montefiore neighborhood and at Tachkemoni, Bilu and Municipal High School A. His father, Avraham Yehezkel, a native of Old Jerusalem, married Rivka Kaminer, of Vawkavysk, Belarus. Together they established a Religious Zionist home in Tel Aviv, and they had ten children, of whom Hayim was the third.
He joined Lehi on the Sabbath of his bar mitzvah celebration. He put up posters, disseminated promotional materials, and observed nightly movements of the British Army and of the trains.
Hayim was one of the Raanana youths, who were being trained with firearms. Informers revealed their location to the British Army, which surrounded the location and slaughtered the participants. Hayim, however, managed to escape to a nearby orchard. When he was captured, he claimed that he had merely come to look for work harvesting. He was then detained in many places: Jaffa’s Kishleh, the Jerusalem Central Prison, Latrun B and Latrun A. Finally, he was released due to lack of evidence.
He then returned to the underground, working in recruitment in Gush Dan and the south. When Lehi stopped working in secret, he joined Dr. Eldad’s Sullam.
In 5710 (1950), he established Brit Kanna’im, which looked to continue Lehi’s path politically, but also to make Israel a religious state. Eventually, he negotiated with the religious underground HaMahaneh in Jerusalem, which had a similar goal, as well as the Tzrifin Underground, which saw itself as Lehi’s successor. The Tzrifin Trial put an end to this. Hayim was indicted, but he was acquitted due to lack of evidence. Brit Kanna’im was disbanded after the Hazon Ish spoke with Hayim at length.
To support himself, Hayim worked as a teacher in the Negev. After three years, he was referred to the Rashi School in Jaffa. After seven years, he became principal, and he remained an educator until he retired.
Hayim married Miriam Shelley. They had six sons: Nahshon Yeshayahu, Pinchas, Shimon Meir, Avraham Yehezkel, Menahem Eliyahu and Gad Yair.
Since retirement, Hayim has spent his time in Torah study and writing.
