Revelation 18:8, 21

8 "Therefore in one day her plagues will overtake her: death, mourning and famine.   She will be consumed by fire, for mighty is Yahveh the Almighty Ones who judge her." . . .

21 Then a mighty angel picked up a boulder the size of a large millstone and threw it into the sea, and said: "With such violence the great city of Babylon will be thrown down, never to be found again."
