'Book' in the Bible

Now as for these four young men, God gave them knowledge and made them expert in all book-learning and wisdom: and Daniel was wise in all visions and dreams.

No one has the courage to support me against them except Michael, your prince. However, I will tell you what is recorded in the book of truth. >

And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.

But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
