According to Rabbi Judah (cited in the Talmud, Bava Metzia 106b), Tevet 29 marks the end of winter. (As per Genesis 8:22, the year consists of six 2-month "seasons": seedtime, harvest, cold, heat, summer and winter.)
Rabbi Yitzchak Kaduri, known in recent years as "the eldest of the Kabbalists," in the Holy Land, was born in Baghdad, Iraq in 1898. As a youth, he studied under the great "Ben Ish Chai" (Rabbi Yosef Chaim of Baghdad, 1840-1913) and was regarded as an illu (prodigy) by the sages of the venerable Baghdad Jewish community. In 1922, Rabbi Yitzchak emigrated to the Holy Land and joined the ranks of the Jerusalem Kabbalists, even as he earned his living for many years as a bookbinder. Over the years his fame grew, and thousands flocked to him to receive his counsel and blessing.
Rabbi Kaduri passed away on the 29th of Tevet of 2006, age 108. Hundreds of thousands attended his funeral in Jerusalem.
In 1793, Tripoli (in what is now Libya) fell under the rule of the cruel Ali Burghul, who took advantage of divisions within the local leadership to take control of the city. Burghul terrorized the city’s inhabitants—especially the Jews—with excessive taxes and unjust executions. Among those executed was the son of R. Abraham Khalfon, the head of the Jewish community.
In 1795, a local Jew helped negotiate an agreement between the opposing factions, and on 29 Teves they succeeded in driving Burghul out of the city. The community celebrated this day each year as a day of rejoicing, and would recite a special hymn recounting the miracle (printed in Se’u Zimrah, pp. 191ff.).
The community of Tripoli kept a similar date of rejoicing one week earlier, on 23 Teves, commemorating the date (in 1705) when a siege that had been placed on the city by the ruler of Tunisia was lifted.
Naturally, we think of the Jewish people as a conglomerate of many Jews. But the Baal Shem Tov saw the Jewish people as a single, indivisible whole.
Think of a geometrical point. A point is indivisible, but not because it is too hard, too big, or too small to cut up. A point simply has no area to be divided. That’s what makes it a point.
And yet, from a point you can extend infinite lines radiating in infinite dimensions.
In a somewhat similar way, but far beyond, all Jews are one Jew. Which means that in any one Jew, you will find all of us—just from a different angle.
So that whatever happens to any one of us instantaneously happens to the entire Jewish people. Not by some ripple effect or resonance. But because any one sample of the whole is the whole and the whole is one.
And so, the Baal Shem Tov taught, when the light of any one Jewish soul breaks free, the entire nation is redeemed along with it.
And accordingly, the Rebbe wrote, the ultimate exodus of our entire people is also a personal, intimate liberation for every Jew.
