Leolai makes perfect sense here. Sometimes a cigar really is just a cigar.
Underneath all the WT posturing on this subject is revealed something of the WT "research" into biblical mystery. Where it might be obvious just to accept what the OT says - for the WT, they quite often get involved into some twisted explanation and then dogmatically INSIST that this is the only way to view this tale. It would have been just as easy to merely SUGGEST that maybe she became some sort of nun, while also honestly saying that they simply do not know!
But that is not the WT way, is it? NOOOO - for example, there is no sure way to prove that Jesus is somehow the personna Michael the Archangel - but once the fixation on this idea was in place, it became holy law to the watchtower.
144,000? No - it simply does not make it clear what this really refers to. Watchtower thought up a theory, and suddenly it is immutable doctrine.
