Revelation 18:20-21

20Yes, you who live in heaven, be happy! Be happy because God has punished Babylon! God's people and his apostles and his prophets, be happy! God has punished the city because of what she did to you.

21Then a powerful angel picked up a very big, heavy stone. He threw it into the sea. He said, ‘God will throw you down, Babylon! You are a great city, but God will throw you down like this stone. Nobody will ever see you again!
