'Book' in the Bible

Then said I, Lo, I am come; In the roll of the book it is written of me:

Thou numberest my wanderings: Put thou my tears into thy bottle; Are they not in thy book?

Let them be blotted out of the book of life, And not be written with the righteous.

Thine eyes did see mine unformed substance; And in thy book they were all written, Even the days that were ordained for me , When as yet there was none of them.
