Hayom Yom: Elul 12

The long hemsheich (series of maamarim) known as "B'sha'a shehikdimu, Te'erav" was begun1 by my father on the first day of Shavuot 5672 (1912) in Lubavitch. He finished it on the Shabbat of parsha Vayeira 5676 (1915) in Rostov - with the maamar which begins VaHashem amar. The hemsheich contains 144 maamarim.

Extant in manuscript2 is a second section which he had not delivered orally, and which is not divided into maamarim.
