On this date, Rabbi Schneur Zalman of Liadi, who supported and aided the Czar's army during the Napoleonic wars, was forced to flee his hometown from Napoleon's forces which were advancing through White Russia in their push toward Moscow. After five months of wanderings he arrived in the town of Pyena. There he fell ill and, weakened by the tribulations of his flight and the harsh Russian winter, passed away on the 24th of Tevet, 5573 (1812).

R. Eliezer Zusia Portugal (1898–1982), the Skulener Rebbe, is best known for his superhuman efforts to rescue Jewish orphans and refugees in Eastern Europe before, during, and after World War II and his continuing support of them. He immigrated to the United States in 1960, after imprisonment in Rumania and international efforts to secure his release. He was renowned for his lengthy prayers and the beautiful tunes he composed.
Everything a human being is given comes in a finite package. Even the tablets Moses carried down from Mount Sinai were defined and bounded.
And so, when G‑d saw Moses mourning over the broken tablets, He said, “Your powers were focused when you smashed the tablets. For now you will receive a Torah you may extend wider than the sea.”
When a human being fails, he shatters the treasures G‑d has put in his trust. But then he cries and picks up the shards to restore what he has ruined.
That is when he discovers that G‑d Himself was hidden inside.
That is when he discovers the Infinite.
