The very facts that none of the original books in the Old Testament exist today, and all extant sources (ie literary evidences, manuscripts, scrolls, papyri, etc, of Masoretic Texts, Dead Sea Scrolls, Septuagint, Samaritan Torah, Vulgate Bible, etc) demonstrably of different versions of the Old Testament, where inconsistencies and errors are found, make the bible not infallible and not inerrant.
And the translations (eg KJV, NASB, NRSV, NIV, NJPS, etc) that we read, especially of the English-speaking backgrounds, are largely dependent on the Masoretic Texts as primary source, and depending on which translations you read, they are supplemented with Septuagint to various degrees.
So there might be contextual variants to these translations.
Those different sources that are still extant, those different translations, and the errors and inconsistencies that can be found in each and every one of them. All of these are evidences that make the Bible not infallible.
If anyone is closed-minded, BB, it is you, because you refused to see the evidences.
