Names not written in the book

Whose names are not written in the book of life from the foundation of the world, Revelation 17:8.

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 the world, Revelation 13:8.

The second reference identifies the book of life with the "lamb slain."

I believe that here and in the 17.8 reference that the prepositional phrase "from the foundation of the world" modifies "written."

The idea would be that the names of these people have not been written in the book from creation (from the foundation of the world) to the time referenced (being the great tribulation period); in other words, "from" has the idea of "since then" to the time being referenced.

Another "from the foundation" reference also has the idea of "since," being Luke 11.50: that the blood of all the prophets which was shed from the foundation of the world may be required of this generation.

That generation of Israel would suffer the consequences for all the prophets that were slain since the foundation, that is, since the beginning of the world.
