Revelation 5:8

5:8 and when he had taken the scroll, the four living creatures and the twenty-four elders threw themselves to the ground before the Lamb. Each of them had a harp and golden bowls full of incense (which are the prayers of the saints).

Revelation 14:2

14:2 I also heard a sound coming out of heaven like the sound of many waters and like the sound of loud thunder. Now the sound I heard was like that made by harpists playing their harps,

Revelation 19:1-7

19:1 After these things I heard what sounded like the loud voice of a vast throng in heaven, saying,

“Hallelujah! Salvation and glory and power belong to our God,

19:2 because his judgments are true and just.

For he has judged the great prostitute

who corrupted the earth with her sexual immorality,

and has avenged the blood of his servants poured out by her own hands!”

19:3 Then a second time the crowd shouted, “Hallelujah!” The smoke rises from her forever and ever. 19:4 The twenty-four elders and the four living creatures threw themselves to the ground and worshiped God, who was seated on the throne, saying: “Amen! Hallelujah!”

19:5 Then a voice came from the throne, saying:

“Praise our God

all you his servants,

and all you who fear Him,

both the small and the great!”

The Wedding Celebration of the Lamb

19:6 Then I heard what sounded like the voice of a vast throng, like the roar of many waters and like loud crashes of thunder. They were shouting:

“Hallelujah!

For the Lord our God, the All-Powerful, reigns!

19:7 Let us rejoice and exult

and give him glory,

because the wedding celebration of the Lamb has come,

and his bride has made herself ready.
