This Book is The Book of Life
Whoever had sinned against YHWH would be blotted out of this book.
In the Testimony of the Old Covenant we find the following:
Then Moses returned to the Lord and said, “Oh, these people have
committed a great sin, and have made for themselves a god of gold! Yet
now, if You will forgive their sin—but if not, I pray, blot me out of
Your book which You have written.”
And the Lord said to Moses, “Whoever has sinned against Me, I will
blot him out of My book. Now therefore, go, lead the people to the
place of which I have spoken to you. Behold, My Angel shall go before
you. Nevertheless, in the day when I visit for punishment, I will
visit punishment upon them for their sin.”
From this passage we learn what leads to one being blotted out of this book--sinning against YHWH God.
Let them be blotted out of the book of the living, And not be written
with the righteous.
From this passage we learn that this book that folks may be blotted out of is the Book of the living in which the righteous are listed.
This is a key passage for discerning what the Hebrews understood this book to be. It was not just a book of the Hebrew dwelling in Jerusalem, but of the living righteous.
Your eyes saw my substance, being yet unformed. And in Your book they
all were written, The days fashioned for me, When as yet there were
none of them.
from this we learn that folks are written in it before they are even formed when as yet their days were not yet.
And it shall come to pass that he who is left in Zion and remains in
Jerusalem will be called holy--everyone who is recorded among the
living in Jerusalem.
This may be the same book unless an earthy book listing the residents of Jerusalem was made.
In the Testimony of the New Covenant We find:
And I urge you also, true companion, help these women who labored
with me in the gospel, with Clement also, and the rest of my fellow
workers, whose names are in the Book of Life.
From this we learn that this book had significance under the New Covenant as well.
He who overcomes shall be clothed in white garments, and I will not
blot out his name from the Book of Life; but I will confess his name
before My Father and before His angels.
here we learn that overcomers are not blotted out of the book of life and that Jesus confesses the names of those in this book before His Father and His angels.
All who dwell on the earth will worship him, whose names have not been
written in the Book of Life of the Lamb slain from the foundation of
here we learn that even those not written in the book of life will worship the Lamb, to whom this book belongs.
The beast that you saw was, and is not, and will ascend out of the
bottomless pit and go to perdition. And those who dwell on the earth
will marvel, whose names are not written in the Book of Life from the
foundation of the world, when they see the beast that was, and is not,
and yet is.
In this parallel passage, we gain insight about how the sentence structure of Revelation 13:8 should be translated, in the absence of "the lamb slain" we discover that it is "the book of life from the foundation of the earth," not "the lamb that was slain from the foundation of the earth."
And I saw the dead, small and great, standing before God, and books
were opened. And another book was opened, which is the Book of Life.
And the dead were judged according to their works, by the things which
were written in the books.
here we learn this book of life is different from the books that were opened by which the dead are judged.
And anyone not found written in the Book of Life was cast into the
lake of fire.
here we learn the fate of those not written in the book of life.
But there shall by no means enter it anything that defiles, or causes
an abomination or a lie, but only those who are written in the Lamb's
Book of Life.
and if anyone takes away from the words of the book of this prophecy,
God shall take away his part from the Book of Life, from the holy
city, and from the things which are written in this book.

--All who are born are already written in this book.
(Note: they are not written in it upon salvation from sins).

(Note: Jesus is the Lamb of God who takes away the sins of the world).
--Overcomers will not be blotted out of the book.

(Note: whoever believes in the Lamb to whom this book belongs may live forever).
