The Jews were masters at this, probably still are, re-telling the stories of their scriptures and making them applicable to their day.
Often the stories would be changed considerably from the earlier versions to make the lesson contempory.
In my opinion that is a very good use of scripture, but no Jew would be looking for a literal fulfillment in his own day, he would simply be learning how to live, by the lessons of the past.
The WT has no mandate to interpret the Bible the way they do, in fact the WT has no mandate to do anything at all, only what 7plus million members allow them to do.
