Revelation 5:6

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 5:12-13

5:12 all of whom were singing in a loud voice:

“Worthy is the lamb who was killed

to receive power and wealth

and wisdom and might

and honor and glory and praise!”

5:13 Then I heard every creature – in heaven, on earth, under the earth, in the sea, and all that is in them – singing:

“To the one seated on the throne and to the Lamb

be praise, honor, glory, and ruling power forever and ever!”
