Revelation 5:8-11

And when he took the scroll, the four living beings and the twenty-four elders fell down before the Lamb. Each one had a harp, and they held gold bowls filled with incense, which are the prayers of God’s people. And they sang a new song with these words: “You are worthy to take the scroll and break its seals and open it. For you were slaughtered, and your blood has ransomed people for God from every tribe and language and people and nation. And you have caused them to become a Kingdom of priests for our God. And they will reign on the earth.” Then I looked again, and I heard the voices of thousands and millions of angels around the throne and of the living beings and the elders.
