Revelation 5:11-13

11Then I looked again, and I heard the voices of many angels. There were thousands and millions of them. They were standing around the throne, with the beings that are alive and the leaders.

12They all sang with loud voices: ‘The Lamb that people killed is completely good! He has all authority, and all things belong to him. He is wise and powerful. Everyone must agree that he is great! Everyone must praise him and worship him!’

13Then I heard everything that is alive singing. That was everything in heaven and everything on the earth, and everything under the earth and everything in the sea. They were singing: ‘We praise the one who sits on the throne. We praise the one who is the Lamb. We say that they are great! We worship them! They have power to rule for ever!’
