Avraham was born in 4.8.1911, in Utena, Lithuania, to Yehuda Dov and Batya. In 1925, the family made aliyah and settled in Tel Aviv. Avraham studied in Gymnasium Geula, and from his youth he was drawn to nationalist circles in Tel Aviv. In 5689, he participated in protests by the Western Wall, and in October 1930, against Under-Secretary of State for the Colonies Drummond Shiels and against the pursuit of the those making aliyah illegally by the British authorities. He joined Beitar in Rosh Pina, and he was even its commander, participating in smuggling immigrants via Syria and Lebanon. He was arrested by the British, and he was the first to claim that they had no right to judge Jews in the Land of Israel.

He was one of the founders of the “nationalist cells,” a member of Brit HaBiryonim, and participated in a number of different activities. He was also active in the communal-social sphere, founding Hazit Poalim Leumit. In 1937, he and his comrades signed up for it to join the Histadrut as a party. He was arrested and detained a number of times, in Acre, Jerusalem, Mizra and Latrun. He wrote many songs which the fighters would sing: Hora Mizra, Gil Israel, Hora Aggada and Knockout. He published articles in the underground periodicals, mainly in HeHazit.

His writings expressed a pure nationalist ideology, emphasizing Greater Israel, and despite his being unaffiliated with religion, he saw the Bible as model for life, mainly the promise “from the River of Egypt until the Euphrates River.” He did not see this as a religious myth, but rather a proof to the geopolitical reality of the region. His passionate and uncompromising nationalist faith was integrated with the pursuit of social justice. He saw himself as being a part of the working class and the workers’ camp.

In 1945, Avresha was freed from detention and immediately joined his comrades in Lehi, and in the coming years, until the State was established and the underground was disbanded, he was very active in internal ideological debates. He even took part in contact with foreign actors, which Lehi established in the intermediate time of 1947-1948.

After the State was established, he worked for a bit in the Ministries of Housing and Labor. Even then, he protested the harsh manual labor which new immigrants were expected to do, instead of getting them ready for creative work. For this reason, he did not last long as a government worker.

He published a monthly, Eretz Israel, as well as a book, HaMizrach HaIvri. To make his living, he wrote crosswords and riddles for the daily papers. He published two books: Hishuvei Pele and Malkhut Egged Har, featuring math problems and riddles respectively. After his death, a volume of his poetry was published.

Avresha passed away on 17.12.1976.

He left a wife, Gelila of Rosh Pina, as well as three daughters and a son.
