What's interesting about that is it's obviously only referring to the book of Revelations itself, since "The Bible" as such didn't even exist at the time, if it isn't a late addition. Yet Christians apply it to scripture as a whole.
Also, IIRC, Revelations almost didn't even make it into the Biblical canon, like a lot of other apocryphal books it was considered too crazy for the mainstream.
"The Bible" is a Christian invention. What existed was the Torah and other Hebrew texts, whose incorporation into Christian canon is based on retroactive continuity, and has never been recognized as valid within Judaism.
