If your husband is such a beautiful person then you should follow his lead and listen and learn from him.
I am more than happy to address your sincere and humble questions regarding such a complex and confusing subject of chronology which is not for the fainthearted but the strong.
Celebrated WT scholar for decades have shown the impossibility of Jerusalem's destruction in 587 or the preferred date of 586 BCE. This is because such chronology which is based solely on secular evidence ignores the biblical seventy years. Such ignorance created a gap of some twenty years between biblical and secular chronology, God or man's chronology. Which one will you prefer?
The biblical and secular evidence proves that Jews did return in 517 but in 537 BCE although some advocate 538 BCE. This means that from 537 BCE we count back the full seventy years which establishes very nicely, ever so nicely the year of 607 BCE.
Scholars and the testimony of Ezra does not allow for 517 as the year for the Return because the seventy years ended the exile, servitude and desolation which could be achieved by the fact of a return back home and the eventual establishing true worship with a rebuilt temple. I hope this is simple enough and my advice is for you to learn more and study hard the Bible and the wonderful publications of the faithful and discreet slave.
