Tula! Keep up the good research and line of thinking! Who really knows, did the bodies raise up then go into the city? Perhaps, after an earthquake the bodies thrown out of their grave, and the people standing around who witnessed the event went back into the city and preached to the people what had happened to Jesus!
Everytime I read that verse, it really does appear that their was a resurrection of the holy ones! I use to think that the raised holy ones were proof that their would be a future resurrection! It's a brain teaser!
At least your looking at the scripture! good topic. Oh have you looked into some commentairies at the library or book store? Interesting how the NWT reads compared to the WT. LOL
