I also found an instance in the book of Job, chapter 3:1-19. Jobs children seem to be celebrating a birthday when the tornado came and collapsed the house killing them all. The Satan's tornado did its job on Job's kids, not because they were celebrating a birthday, but because Jehovah apparently gave Satan permission to kill them as a test for Job. Nevertheless, Job and his family DID seem to celebrate birthdays. Job's burnt offering to Jehovah the next morning was not to atone for the sin of celebrating a birthday, but just incase his brats were sinning while having the party, " That is the way Job would do always."
That's just it... whenever an elder or husband says a prayer for the congregation or family, does he not usually ask for forgiveness of their sins, whether or not they are aware of committing one? It's a "just in case" kind of thing, right?
My thoughts on the birthdays is that JWs have twisted around the reason why bdays are mentioned in the Bible... think about it, in the case of Pharoah's killing the baker at his birthday, could it be that it was written as proof that Joseph's intrepretation of a dream had come true? Isn't that the story that was being told anyway? The bday event was just a coincidence, how it worked out. Again, in the case of John the Baptizer's death, could it simply be that the Bible writers were letting people know how he died, what happened to him, just like anyone else important whose death they recorded (ie. Stephen)? The bday is just a coincidence. The same with Job.. of course, you never hear of that one from JW's because it proves that someone righteous did celebrate birthdays, or didn't care that his kids did. It isn't why they died.
