Mordi was an only child and a relative of the poet Avigdor Hame’iri. He was a member of the movement from an early age. He learned plumbing. Mordi moved to Budapest at the end of 1938 and joined the movement’s leadership. He belonged to the Sela Organization. From 1942 he was active in giving assistance to the refugees arriving in Budapest from Slovakia and took part in the underground activities of his movement. In 1943 Mordi returned to Kassa in order to witness the birth of his son from his wife, Malka Baumøhl. In Kassa he was enlisted in a forced labor unit which was sent to the copper mines in Bor, Yugoslavia where he perished probably in 1944. His wife and son Abraham were shot by the Germans in a forest near Kassa.
