Revelation 5:8-9

8When he had taken the book, the four beings and the 24 leaders fell down to the ground in front of the Lamb. They worshipped him. Each leader had a harp to make music. They were also holding gold bowls which were full of incense. That nice smell shows what it is like when God's people pray to him.

9The beings that are alive and the leaders sang a new song. They sang: ‘You are so good! You are good enough to take the book. You can break its seals and open it. You can do this because they killed you. When you died, you bought people for God with your blood. You bought them from every tribe, from every language and every nation.
