Nachum Avraham is addressed in correspondence from the Lubavitcher Rebbe as an individual actively involved in Torah and Chassidic outreach, particularly within the Jewish community of Antwerp. The Rebbe refers to him with honorifics indicating his dedication to communal and spiritual work.
The Rebbe's letter to Nachum Avraham, dated 3 Elul 5711 (1951), acknowledges Nachum Avraham's recent relocation to Antwerp and his successful establishment of livelihood there. The Rebbe blesses him with continued success, both materially and spiritually, emphasizing the importance of securing time for Torah study.
The Rebbe expresses pleasure upon hearing that Nachum Avraham organized a farbrengen (Chassidic gathering) on the festival of 12 Tammuz, which was marked by inspiration, strengthened Ahavas Yisrael (love of fellow Jews), and a commitment to regular Torah study. The Rebbe encourages Nachum Avraham to ensure that these positive resolutions are implemented in practice and to continue expanding the group, especially by including individuals less familiar with Chassidus.
Guidance is given regarding the study of Chassidus, with the Rebbe recommending foundational texts such as Sefer HaTanya, Derech Mitzvosecha by the Tzemach Tzedek, Kuntres U'Maayan by the Rebbe Rashab, and the simpler discourses of the Previous Rebbe, often found in the pamphlets for 12 Tammuz. The Rebbe requests updates about the group's growth and activities, and sends blessings for a good and sweet new year, extending regards to all members of the group.
