Here are two errors I know of:
Rom 16:7. Junias has been used for many centuries and recently shown to be a tendentious correction by an ancient scribe who apparently could not stomach that a woman would be identified and honored as an apostle.
Luke 2:1-4. People are taxed in the domicile where they reside, not where their ancestors lived. The reason given for Joseph's travel to Bethlehem cannot be the taxation census. Web sites that give reference to an Egyptian document showing otherwise are being dishonest.
