Revelation 5:6-8

6Then I saw a Lamb who appeared to have been slain, standing in the center of the throne, encircled by the four living creatures and the elders. The Lamb had seven horns and seven eyes, which represent the seven spirits1 of God sent out into all the earth. 7And He came and took the scroll from the right hand of the One seated on the throne.

8When He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp, and they were holding golden bowls full of incense, which are the prayers of the saints.
