Rev 5:8-9 8 And when He had taken the scroll, the four living creatures and the twenty-four elders [of the heavenly Sanhedrin] prostrated themselves before the Lamb. Each was holding a harp (lute or guitar), and they had golden bowls full of incense (fragrant spices and gums for burning), which are the prayers of God's people (the saints). 9 And [now] they sing a new song, saying, You are worthy to take the scroll and to break the seals that are on it, for You were slain (sacrificed), and with Your blood You purchased men unto God from every tribe and language and people and nation. [Ps 33:3.] AMP
