Eliyahu Hirsh is addressed in correspondence from the Lubavitcher Rebbe as a Torah-observant individual, recognized for his acts of kindness and communal support, together with his wife, particularly in assisting a local rabbi in a time of need.
The Rebbe's letter to Eliyahu Hirsh, dated 1 Sivan 5711 (1951), expresses gratitude for a letter reporting good news regarding the improved health of a rabbi's wife. The Rebbe thanks Mr. Hirsh for his and his wife's assistance to the rabbi during a difficult period, highlighting this as a fulfillment of the mitzvah of VeAhavta L'Rei'acha Kamocha ("You shall love your fellow as yourself").
The Rebbe elaborates on the centrality of this mitzvah, citing Hillel's teaching that it is the fundamental principle of the Torah. He further conveys the teaching of his father-in-law, the previous Rebbe, in the name of the Alter Rebbe (author of the Tanya), that loving one's fellow Jew is a vessel for attaining love of Hashem. The Rebbe expresses his hope that both love of G-d and love of Israel will be united in Mr. Hirsh's life.
Additionally, the Rebbe shares a teaching from the Tzemach Tzedek on the Hebrew alphabet, emphasizing the importance of love (ahavah) and blessing (berachah), while warning against pride (ga'avah) and poverty (dalus). The letter concludes with the Rebbe's blessing that Mr. Hirsh should accept the Torah with joy and inwardness for the coming year, in anticipation of the festival of Shavuos.
