'Book of Life' in the Bible

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

yea, I ask thee also, true yokefellow, assist them, who have contended along with me in the glad tidings, with Clement also, and my other fellow-labourers, whose names are in the book of life.

He that overcomes, he shall be clothed in white garments, and I will not blot his name out of the book of life, and will confess his name before my Father and before his angels.

and all that dwell on the earth shall do it homage, every one whose name had not been written from the founding of the world in the book of life of the slain Lamb.

The beast which thou sawest was, and is not, and is about to come up out of the abyss and go into destruction: and they who dwell on the earth, whose names are not written from the founding of the world in the book of life, shall wonder, seeing the beast, that it was, and is not, and shall be present.

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

And nothing common, nor that maketh an abomination and a lie, shall at all enter into it; but those only who are written in the book of life of the Lamb.
