Zedekiah was the last king of the royal house of David to reign in the Holy Land. He ascended the throne in 434 BCE, after King Nebuchadnezzar of Babylonia (to whom the kingdom of Judah was then subject) exiled King Jeconiah (Zedekiah's nephew) to Babylonia . In 425 BCE Zedekiah rebelled against Babylonian rule, and Nebuchadnezzar laid siege to Jerusalem (in Tevet 10 of that year); in the summer of 423 BCE the walls of Jerusalem were penetrated, the city conquered, the (first) Holy Temple destroyed, and the people of Judah exiled to Babylonia. Zedekiah tried escaping through a tunnel leading out of the city, but was captured; his sons were killed before his eyes, and then he was blinded. Zedekiah languished in the royal dungeon in Babylonia until Nebuchadnezzar's death in 397 BCE; Evil Meroduch -- Nebuchadnezzar's son and successor -- freed him (and his nephew Jeconiah) on the 27th of Adar, but Zedikiah died that same day.
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.
