Eliash, along with other prominent Jewish lawyers in Palestine, such as Norman Bentwich and Gad Frumkin joined the society, which published two scholarly journals and founded two legal presses.
[6][7] Eliash served as a witness to the Shaw Commission established by the British Mandatory government in December 1929 to investigate the Arab riots against the Jews.
[9][10] Eliash was the ranking member of a Jewish National Council delegation representing the Jews' position to the Anglo-American Committee of Inquiry.
[14] After Britain granted Israel de facto recognition, Eliash returned to London on April 5, 1949, to begin service as ambassador.
[13] The appointment of the religious Eliash to the post was regarded as a sensitive gesture, as the Jewish Agency had neglected relations with synagogues in the United Kingdom.
According to scholar Natan Aridan, Eliash's regular appearances, including leading prayers, at the St John's Wood United Synagogue, an influential center of Anglo Jewry, was a key factor in improving ties with the Jewish community.
[15] Eliash was stabbed in the throat and chest by two men, who he believed to be Jews, while walking the streets of Jerusalem on January 30, 1936.
[citation needed] In 1953, a stained glass window at St. John's Wood United Synagogue was dedicated in Eliash's memory.
The synagogue also dedicated windows to first President of Israel Chaim Weizmann and Zionist leader Theodor Herzl.
