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.

Failure is wasted if you return only to the place from where you fell.
