The founder of Chabad Chassidism, Rabbi Schneur Zalman of Liadi (1745-1812), passed away on the eve of the 24th of Tevet, 5573, at approximately 10:30 pm, shortly after reciting the Havdalah prayer marking the end of the Shabbat. The Rebbe was in the village of Peyena, fleeing Napoleon's armies, which had swept through the Rebbe's hometown of Liadi three months earlier in their advance towards Moscow. He was in his 68th year at the time of his passing, and was succeeded by his son, Rabbi DovBer of Lubavitch.

A devastating earthquake struck northern Israel, killing four thousand Jews in Safed and between 700 to 1000 Jews in Tiberias. Many of the survivors migrated to Hebron, rejuvenating the developing Chabad community established there 10 years earlier by the second Rebbe of Chabad, Rabbi DovBer of Lubavitch.
One of the first hospitals in America under Jewish direction, Mount Sinai Hospital, was founded in New York on this date in 1852.
As you treat others here below, so you are treated above.
Perhaps someone once tried to tell you about the ugly deeds of another.
You really wanted to hear. But you knew that’s not right. Gossip is a form of murder, and you did not wish to be an accomplice.
Mustering all your moral strength, you quietly responded, “I’m not interested.”
And you didn’t listen.
So you will be treated above.
When your soul returns to its place above, a prosecuting angel will appear to report on your deeds down here. And it’s possible that some of those deeds may also not have been so pretty.
But just as you responded, so too G‑d will also say, “I’m not interested. I don’t even want to listen.”
The sweat was worthwhile.
