Halevy believed that his role as a representative in the Municipality of Hamadan could provide a measure of security against arbitrary persecution, particularly by the Shiite majority.
To support this mission, Halevy authored pamphlets, delivered sermons in the synagogue, and established organizations aimed at reintegrating those who had experienced forced conversion.
He became a prominent figure in the Iranian congregation and held key roles in organizations such as the Vaad HaSephardim and the Histadrut Haluzei HaMizrachi of Jerusalem.
As an emissary for Keren Hayesod and HaMizrachi, he traveled extensively to locations including Aden, Beirut, Sidon, Damascus, and Egypt.
On February 3, 1939, the Mizrahi organization World Central expressed their gratitude to Halevy for founding a Mizrachi branch in Bombay and acknowledged the significance of his meeting with Gandhi.
