Hello Garry B, John and Doves,
I didn't really answer your question I just noted where, when and why I thought the gap was inserted....
Did God intend?
Of course God knew this would all happen...and He had a plan for it. I don't think He intended it. His plan/prophecy was for His people and Jerusalem...they didn't go along with it very well...so I think God works around what we humans do as we mess things up. Like He always has a Plan B.
Just my thought for now on your question.
Maranatha!
