The last clause of verse 12, Kings 24 has always appeared to me to be somewhat ambiguous,
"and the King of Babylon got to take him (Jehoiachin) in the eighth year of his being King." This has lead to the genneral connection of Nebuchadnezzar's eighth year to the start of Zedekiah's rule and thus to the equating of Nebuchadnezzar's nineteenth year with Zedekiah's eleventh.
The CEB reads, " The Babylonian King took Jehoiachin prisoner in the eighth year of Jehoiachin's rule."
This translation removes the only connection between Babylonian Kings regal years and those of Judea in the book of Kings and leaves connection in Jerimiah and Daniel both of which directly apply to Jehoikim only. It does however contradict 2Kings 24:8 " and for three months he reigned in Jerusalem." but this could easily indicate a co reign starting at the end of Jehoiakim's third year at the time of his three years servatute in the accension year of Nebuchandrezzar 2Kings 24:1, 2Chronicles 35:6,7, and Daniel 1:1,2 and giving rise to Daniel's own exile.
In addition it makes the readings of Jermiah 39: 1-10 which has no mention of the destruction of the Temple in the fourth month eleventh year of Zedekiah and Jer 52: 12-27 in the fifth month "that is the nineteenth year Nebuchadrezzar" which doesdetail the burning and looting of the Temple, and the capture of senior officials of Judea, in addition to a military force. The presence of these officials and only sixty men in the city at this time is in accord with the exile of the populus the year before, and their fate could well indicate insurrection as mentioned in Ezekiel 33: 24 five months earlier. In verses 28-30 concerning the exiles of Nebuchadrezzar's seventh, eigteenth, and twenty third years now fit into the their respective years with no need for complecated adjustment to the chronological system and no confussion.
The only issue that I have forseen is that historians will endevour to stick to the 609BCE date for the death of Josiah dispite a total lack of any evidence for such a date. This event has just as much evidence for being placed mid 608BCE or early 607BCE as Egypt was still just as active in the area as they had been in 610 and 609BCE if not more so with the greater threat from Babylon and no Assyrian buffer state to protect invasion across the Euphrates.
Can anyone show how the MT should be tranlated and why, and also the LXX although I have looked at this and with my limited understanding of Greek the LXX agrees with the CEB however I could well be wrong.
