'Written in the Book' in the Bible

The beast that you saw was, and is not, and is going to come up from the abyss, and he is going to destruction. And those who live on the earth, whose names are not written in the book of life from the foundation of the world, will be astonished [when they] see the beast that was, and is not, and will be present.

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.

And if anyone was not found written in the book of life, he was thrown into the lake of fire.

And every unclean thing and one who practices detestable things and falsehood will never enter into it, except those who are written in the book of life of the Lamb.
