'Written in the Book' in the Bible

And all the inhabitants of the earth shall worship it, whose names are not written in the book of life of the Lamb, that was slain from the beginning of the world.

The beast which you saw, was, and is not; and he will ascend out of the bottomless pit, and go to destruction; and the inhabitants of the earth (whose names are not written in the book of life, from the foundation of the world) shall wonder, seeing the beast who was, and is not, yet shall be.

And I saw the dead, small and great, standing before God; and the books were opened: and another book was opened, which is the book of life; and the dead were judged out of the things written in the books, according to their works.

And if any one was not found written in the book of life, he was cast into the lake of fire.
