The Bible overall, but especially Genesis, is a collection of stories. These stories were stitched together (either by man or God, it doesn’t matter) to make theological or historical points. I’ve made a big deal out of ages and timelines in the last couple of posts because I love facts. I love nuggets of information that I can hold on to and draw context with. Genealogical tables, lists of place names, and timelines all fascinate me in the bible and I’ve done posts about all three.
The truth is though, that sometimes it seems like the author didn’t care about all of that. Some stories appear to be spiritually true more than they are historically true, or even true relative to other stories. This happens in the Proverbs (some of which directly contradict each other), this happens in Numbers (the inflated population figures), and it happens in Genesis. The ages of Isaac and Ishmael is one of those “truths”.
What do I mean? Well, I guess you’ll have to keep reading…
