Revelation 5:8-11

ISV(i) 8 When the lamb had taken the scroll, the four living creatures and the twenty-four elders bowed down in front of him. Each held a harp and a gold bowl full of incense, the prayers of the saints. 9 They sang a new song: “You are worthy to take the scroll and open its seals, because you were slaughtered. With your blood you purchased people for God from every tribe, language, people, and nation. 10 You made them a kingdom and priests for our God, and they will reign on the earth.”
11 The Vision of the Song of the LambThen I looked, and I heard the voices of many angels, the living creatures, and the elders surrounding the throne. They numbered 10,000’s times 10,000 and thousands times thousands.
