This is the transcript of Splane's explanation of Exodus 1:6 from the September 2015 broadcast.
Around 2:50 in September 2015 broadcast.
Now if you were asked by someone to identify a scripture that tells us what a generation is, what scripture would you turn to? I'll give you a moment. Think about that.
My choice is Exodus 1:6. Let's read that. Exodus 1:6.
Joseph eventually died, and also all his brothers, and all that generation.
Now what do we know about Joseph's family? We know that Joseph had 11 brothers, 10 of them were older than Joseph. One of them, Benjamin, was younger. And we know that at least two of Joseph's brothers actually lived longer than Joseph because the bible says that that on his deathbed he called his "brothers", plural, to him.
Now what did Joseph and his brothers all have in common? They were all contemporaries. They had all lived at the same time. They were part of the same generation.
Now suppose there was a man who died 10 minutes before Joseph was born. Would he be part of Joseph's generation? No, because he'd never lived at the same time as Joseph. He was not a contemporary of Joseph's. Now suppose there was a little baby who was born 10 minutes after Joseph died. Would the baby be part of Joseph's generation? Again, no, because the baby would not have lived at the same time as Joseph. For the man and the baby to part of Joseph's generation they would have had to have lived at least sometime during Joseph's lifespan.
So now we've discovered what it means to have a generation, what makes up a generation, it's a group of contemporaries. It's a group of people who have lived at the same time.
As you can see, it's already a very specific and unusual definition of a generation to cover only people that lived at exactly the same time even if the overlap is very small. If you read that scripture and asked someone what a generation was, would anyone interpret that as anyone that was born within a 110 period, even if they then went on to live another 50,60 years?
The point that actually Joseph's brothers were very close in age is consistent with a more typical understanding of a generation as those peers of yours, those around a similar age. I wonder if the WTS has used this scripture with this understanding in the past to attempt to justify previous beliefs where the generation was more like 70 years or so?
