Revelation 5:8-10
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).
5:9 They were singing a new song:
“You are worthy to take the scroll
and to open its seals
because you were killed,
and at the cost of your own blood you have purchased for God
persons from every tribe, language, people, and nation.
5:10 You have appointed them as a kingdom and priests to serve our God, and they will reign on the earth.”
