'Foundation of the World' in the Bible

All the inhabitants of the earth will fall down and worship him, everyone whose name has not been written since the foundation of the world in the Book of Life of the Lamb who has been slain [as a willing sacrifice].

“The beast that you saw was [once], but [now] is not, and he is about to come up out of the abyss (the bottomless pit, the dwelling place of demons) and go to destruction (perdition). And the inhabitants of the earth, whose names have not been written in the Book of Life from the foundation of the world, will be astonished when they see the beast, because he was and is not and is yet to come [to earth].
