Scholar reared his head yet again...
the Jonsson hypothesis with its unsustainable 586/587 for the Fall of Jerusalem.
Dude,
There is no Jonsson hypothesis. Jerusalemn did fall in 586/587. No one outside the Watchtower questions this. There is no evidence that would suggest this date is off by 20 years. There is overwhelming evidence that points to this being the correct date. See Let Your Kingdom Come, appendix to chapter 14, published by Watchtower Bible and Tract Society 1981.
No Apologies
