Chronicle Concerning the Early Years of Nebuchadnezzar II

Chronicle Concerning the Early Years of Nebuchadnezzar II: "Nebuchadnezzar took Jehoiachin to Babylon, along with his mother, his wives, his officials, and the most important leaders of Judah. He also led away 7,000 soldiers, 1,000 skilled workers, and anyone who would be useful in battle. Then Nebuchadnezzar appointed Jehoiachin's uncle Mattaniah king of Judah and changed his name to Zedekiah.

The date in this Biblical story (the eighth year of Nebuchadnezzar) is contradicted by this chronicle and the Biblical book of Jeremiah, which both state that it was the seventh year:

Here is a list of the number of the people of Judah that Nebuchadnezzar took to Babylonia as prisoners: in his seventh year as king, he took 3,023 people; in his eighteenth year as king, he took 832 from Jerusalem; in his twenty-third year as king, his officer Nebuzaradan took 745 people. So, Nebuchadnezzar took a total of 4,600 people from Judah to Babylonia.
[Jeremiah 52.28-30
