For those unfamiliar with the issues, a very brief historical overview is in order. We are basically dealing with events that span roughly 125 years, from 625 B.C.E. to 500 B.C.E. It includes the end, or fall, of the Assyrian Empire to Babylon in 609 B.C.E. followed by the rise and subsequent end, or fall, of the Neo-Babylonian Empire (Babylonian Empire) which lasted seventy years, followed by the rise and early years of the combined empires of the Persians and Medes which ended Babylon’s reign in October 539 B.C.E.
We are especially concerned with the Jews of Jerusalem and Judah during this time who were caught between these rising and falling empires, particularly the seventy-year period defined here as the Babylonian Empire. These Jews would come to serve Babylon in various capacities, as did all the surrounding nations that fell under the dominion of the Babylonians, or Chaldeans.
There were numerous Babylonian kings during this era, beginning with Nabopolassar who presided over the final demise of Assyria in 609 B.C.E., followed by his son Nebuchadnezzar (or Nebuchadrezzar), the great warrior king who consolidated the empire through numerous military campaigns. It was Nebuchadnezzar who enslaved the Jews, forced them to become vassals, dispersed them to other nations, exiled them to Babylon and annihilated or devastated Jerusalem and Judah. The end of the Babylon Empire was presided over by Nabonidus who was then king, though his son Belshazzer was co-ruler of Babylon when the Persians and Medes conquered them in October 539 B.C.E.
Our attention is basically focused on three Jewish kings:
a) Jehoiakim: He ruled eleven years, and had been in power when Nebuchadnezzar ruled in his first year as king of Babylon. Jehoiakim became a vassal to Babylon in his eighth year, rebelled against Babylon, and depending upon which Bible one reads, and other factors, was exiled to Babylon with other Jews (2 Kings 24:1-4).
b) Jehoiachin (also called Jeconiah): His reign replaced Jehoiakim's but lasted only three months at which time he, and 10,000 others - all of Jerusalem - were exiled to Babylon roughly 800 miles away (2 Kings 24:8 - 17).
c) Zedekiah: He replaced Jehoiachin, ruled eleven years, became a vassal to Babylon early on, and steadfastly rebelled against Nebuchadnezzar who then utterly destroyed Jerusalem and Judah in Zedekiah’s eleventh year; he either slaughtered, dispersed or exiled the remaining Jews to Babylon. The Jehovah’s Witnesses believe this destruction of Jerusalem occurred in 607 B.C.E., while everyone else for the most part agrees it occurred in 587/6 B.C.E. See generally Jeremiah chapters 24 and 25.
After the Persians and Medes conquered Babylon in 539 B.C.E. the Jews were set free and roughly 50,000 of them returned home to Judah in the fall of 537 B.C.E.
