God has a funny way of treating his “chosen people.” Apparently, the Jews were misbehaving and being ungodly. After several years of some other shenanigans in Babylon, god decided it was time to put his foot down and end the free will of the king by having him take the Jewish people captive. This was in ca. 597 BCE. First I’d like to ask the following questions: Shouldn’t god have known that his “chosen people” were going to act like brats? Couldn’t he have chosen a better, more well-behaved group of people to whom to deliver his word? Anyway, moving on.
In Jeremiah it is foretold that the Jews will not be able to leave Babylon for 70 years. That’s a fairly long time. It’s an almost guaranteed life sentence for most people.
But wait! What’s the book of Baruch? It’s a deuterocanonical part of the apocrypha that is widely quoted in the bible. It’s also a major part of Jewish, Christian, and Catholic canon. I have linked the Catholic text above. The book of Baruch is generally considered just as infallible as the rest of the bible.
Ahem, in Baruch, we are told that the captivity will last seven generations, not merely 70 years. In order to reconcile these two disparate numbers, the Jews would’ve had to be having children at the age of ten or younger! That’s far too young, even by biblical-day standards.
Of course, they are both wrong. In “reality”* the Babylonian Exile only lasted 60 years.
*In real reality we have no idea whether or not the Babylonian Exile actually took place. It might be just another piece of bible fiction.
