So because this may imply that these Kings could have ruled for longer because there could be other tablets, my spouse closed the case and thinks 607 is still correct. Any thoughts as to where I can go from here? Thanks!
Ask him to draw up a list of kings showing which king was reigning in each year from 625 to 539, quoting his resources for each king.
Remind him that the Awake! referred to here doesn't quibble about the lengths of the reigns of any of them, If he wants to prove that the WT was wrong with the lengths of the reigns or the successions in this Awake! , he needs to have some evidence.
If he tries speculation, get him to read the definition of the word 'evidence' to you from a dictionary. That is a good way to make a lot of points. Don't tell them something they don't want to hear, ask them to read it to you from a source they trust.
Cheers
Chris
