'Books' in the Bible

My son, be careful {about anything beyond these things}. For the writing of books is endless, and too much study {is wearisome}.

A stream of fire issued forth and flowed {from his presence}; thousands [upon] thousands served him and ten thousand [upon] ten thousand stood before him. The judge sat, and [the] books were opened.

Now there are also many other [things] that Jesus did, which--if they were written down one after the other--I suppose not even the world itself could contain the books that would be written.

and many of those who practiced magic brought together [their] books [and] burned [them] up in the sight of everyone. And they counted up their value and found [it was] {fifty thousand silver coins}.

And I saw the dead--the great and the small--standing before the throne, and books were opened. And another book was opened, which is the [book] of life, and the dead were judged by what was written in the books, according to their deeds.
