The beast that you saw was, and now is not, but is about to rise from the abyss and go to destruction. And those who dwell on the earth, whose names have not been written in the Book of Life from the foundation of the world, will (thaumasthēsontai | θαυμασθήσονται | fut pass ind 3 pl) be (thaumasthēsontai | θαυμασθήσονται | fut pass ind 3 pl) astounded (thaumasthēsontai | θαυμασθήσονται | fut pass ind 3 pl) when they see the beast, because he was and is not, but is to come.
