Chronological notes
The Babylonian Chronicles give 2 Adar (16 March), 597 BC, as the date that Nebuchadnezzar captured Jerusalem, thus putting an end to the reign of Jehoaichin . [3] Zedekiah's installation as king by Nebuchadnezzar can therefore be firmly dated to the early spring of 597 BC. Historically there has been considerable controversy over the date when Jerusalem was captured the second time and Zedekiah's reign came to an end. There is no dispute about the month: it was the summer month of Tammuz (Jeremiah 52:6). The problem has been to determine the year. It was noted above that Albright preferred 587 BC and Thiele advocated 586 BC, and this division among scholars has persisted until the present time. If Zedekiah's years are by accession counting, whereby the year he came to the throne was considered his "zero" year and his first full year in office, 597/596, was counted as year one, Zedekiah's eleventh year, the year the city fell, would be 587/586. Since Judean regnal years were measured from Tishri in the fall, this would place the end of his reign and the capture of the city in the summer of 586 BC. Accession counting was the rule for most, but not all, of the kings of Judah, whereas "non-accession" counting was the rule for most, but not all, of the kings of Israel. [2] [4]
The publication of the Babylonian Chronicles in 1956, however, gave evidence that the years of Zedekiah were measured in a non-accession sense. This reckoning makes year 598/597 BC, the year Zedekiah was installed by Nebuchadnezzar according to Judah's Tishri-based calendar, to be year "one," so that the fall of Jerusalem in his eleventh year would have been in year 588/587 BC, i.e. in the summer of 587 BC. The Bablyonian Chronicles allow the fairly precise dating of the capture of Jehoiachin and the start of Zedekiah's reign, and they also give the accession year of Nebuchadnezzar's successor Amel-Marduk (Evil Merodach) as 562/561 BC, which was the 37th year of Jehoiachin's captivity according to 2 Kings 25:27. These Babylonian records related to Jehoiachin's reign are consistent with the fall of the city in 587 but not in 586, as explained in the Jehoiachin/Jeconiah article, thus vindicating Albright's date. Nevertheless, scholars who assume that Zedekiah's reign should be calculated by accession reckoning will continue to adhere to the 586 date, and so the infobox contains this as an alternative.
