Revelation 5:8-10

And when he had taken the book, the four beasts and four {and} twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints. {odours: or, incense} And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; And hast made us unto our God kings and priests: and we shall reign on the earth.
