After this I heard what sounded like a huge crowd in heaven. They said, "Hallelujah! The salvation and glory and power of our God!
References for Revelation 19:1
His judgments are true and just, because he judged the great prostitute, who ruined the earth by her whoring, and he exacted the penalty for the blood of his servants from her hand."
Then they said a second time, "Hallelujah! Smoke goes up from her forever and always."
The twenty-four elders and the four living creatures fell down and worshipped God, who is seated on the throne, and they said, "Amen. Hallelujah!"
Then a voice went out from the throne and said, "Praise our God, all you his servants, and you who fear him, both small and great."
