An "infallible" written account

I sometimes hear people refer to certain written accounts (e.g., the bible) as "infallible". What does it mean to say that some written account is "infallible"?

infallible

–adjective

1. absolutely trustworthy or sure: an infallible rule.
2. unfailing in effectiveness or operation; certain: an infallible remedy.
3. not fallible; exempt from liability to error, as persons, their judgment, or pronouncements: an infallible principle.



Luke 21:33
Heaven and earth shall pass away: but my words shall not pass away.

The word of God is infallible. It won't fail or pass away. Same idea.
