yep that is a stretch truth_about_the_truth. just more dogma that the WTBTS likes to use in order to convince people they are the modern day nation of Israel .I've read the climax book and there are alot of parallels drawn to how they left their captivity and much like the ancient nation were allowed to bring temple treasures back to the temple ( spiritual truths being the temple treasure ).
Also from what I've read they also accuse the apostate religious leaders of paying off those that locked them up . That way they could work the revelation scripture showing that gifts were exchanged , revelation 11:10 . Some guy named Ray H. Abrams wrote a book about the situation in 1933 called Preachers Present Arms. Upton Sinclair also seemed to agree with the assessment but I don't see any facts besides opinions offered .
