They are simply not a part of the revelation. They are a part of the limitations of human language and knowledge.
For example, a reporter might reveal an event he observed in a photograph. That is inerrant, thanks to the physics of the camera and print. However, if you magnify the print of the photograph, you will see dots of red green and blue color that were not a part of the event. They are just the imaging technology. One who would argue that the actual even had a multitude of red, green and blue dots involved because the photograph has then would not be arguing from the inerrancy of the photograph, but from his ignorance of the technology used in photography.
the actual event had a multitude of red, green and blue dots involved because the photograph has them.
Typos that are legitimate words are the worst. There is a lesson in separating the transmission from the content in this as well.
non-theological facts could be in error.
They are simply not a part of the revelation.
And I suppose the fact that Popes have condemned this notion of yours (non-theological matter in the Bible is not inerrant) means nothing to you or to those who think like you. Oh well. We all know so much more nowadays than those primitives did.
Since "Biblical scholars" reject the notion that the Israelites were ever in Egypt to begin with I suppose the Book of Exodus is full of historical errors as well.
