I don’t suppose you realize how petty you sound quibbling about something like this? The ancient Jews didn’t have micrometers and measurements were, of necessity, pretty rough. To demand that an historic account be precise to the n’th degree is to hold the writers of the OT to a standard of perfection that is not demanded of anyone else. Your prejudice is showing.
I thought God was the word of the Old Testament. Now you are telling me that the 'Word of God' is actually the 'Word of Human Writers' and cannot be held to be inerrant.
