It is perfectly valid to say one historical document verifies another historical document.
However Biblical prophecy can also be verified from sources outside the Bible.
Only evidenced documents.
Example of biblical prophecy that are verified outside the bible
For example?
I don't know about you but i think killing men and taking virgin women ad plunder is pretty insulting to humanity
That is an example of someone using the Bible in such a way as to insult my intelligence and the Bible itself and maybe your own intelligence.
No that is away of taking the teachings of the bible and showing that it's not all a petty story, in fact around 85% of it is really quite horrendous.
