A little more insightful information.......
The siege of Jerusalem was a military campaign carried out by Nebuchadnezzar II, king of Babylon, in 597 BC. In 605 BC, he defeated Pharaoh Necho at the Battle of Carchemish, and subsequently invaded Judah. According to the Nebuchadnezzar Chronicle, King Jehoiakim of Judah rebelled against Babylonian rule, but Nebuchadnezzar captured the city and installed Zedekiah as ruler.
To avoid the destruction of Jerusalem, King Jehoiakim of Judah, in his third year, changed his allegiance from Egypt to Babylon. He paid tribute from the treasury in Jerusalem, some temple artifacts and some of the royal family and nobility as hostages. In 601 BC, during the fourth year of his reign, Nebuchadnezzar unsuccessfully attempted to invade Egypt and was repulsed with heavy losses. The failure led to numerous rebellions among the states of the Levant which owed allegiance to Babylon, including Judah, where King Jehoiakim stopped paying tribute to Nebuchadnezzar and took a pro-Egyptian position.
In the seventh year [of Nebuchadnezzar, 598 BC] in the month Chislev [November/December] the king of Babylon assembled his army, and after he had invaded the land of Hatti (Syria/Palestine) he laid siege to the city of Judah. On the second day of the month of Adar [16 March] he conquered the city and took the king [Jeconiah] prisoner. He installed in his place a king [Zedekiah] of his own choice, and after he had received rich tribute, he sent forth to Babylon.
Jehoiakim died during the siege, possibly on December 10, 598 BC, or during the months of Kislev, or Tevet. Nebuchadnezzar pillaged the city and its Temple, and the new king Jeconiah, who was either 8 or 18, and his court and other prominent citizens and craftsmen, were deported to Babylon. The deportation occurred prior to Nisan of 597 BC, and dates in the Book of Ezekiel are counted from that event.
